Business Description and Significant Accounting Policies	Dec. 31, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Significant Accounting Policies	Business Description and Significant Accounting Policies Business Description Oblong, Inc. (“Oblong” or “we” or “us” or the “Company”) was formed as a Delaware corporation in May 2000 and is a provider of patented multi-stream collaboration technologies and managed services for video collaboration and network applications. Prior to March 6, 2020, Oblong, Inc. was named Glowpoint, Inc. (“Glowpoint”). On March 6, 2020, Glowpoint changed its name to Oblong, Inc. On October 1, 2019, the Company closed an acquisition of all of the outstanding equity interest of Oblong Industries, Inc., a privately held Delaware corporation founded in 2006 (“Oblong Industries”); see further discussion in Note 3 - Oblong Industries Acquisition . Principles of Consolidation The consolidated financial statements include the accounts of Oblong and our 100%-owned subsidiaries (i) GP Communications, LLC (“GP Communications”), whose business function is to provide interstate telecommunications services for regulatory purposes, (ii) Oblong Industries, Inc., and (iii) the following subsidiaries of Oblong Industries: Oblong Industries Europe, S.L. and Oblong Europe Limited. All inter-company balances and transactions have been eliminated in consolidation. The U.S. Dollar is the functional currency for all subsidiaries. Segments Prior to the acquisition of Oblong Industries on October 1, 2019, the Company operated in one segment. Effective October 1, 2019, the former businesses of Glowpoint, Inc. (now Oblong, Inc.) and Oblong Industries were managed separately and involve different products and services. Accordingly, the Company currently operates in two segments: 1) the Oblong, Inc. (formerly Glowpoint) business which mainly consists of managed services for video collaboration and network and 2) the Oblong Industries business which consists of products and services for visual collaboration technologies. See Note 15 - Segment Reporting for further discussion. Use of Estimates Preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates made. We continually evaluate estimates used in the preparation of our consolidated financial statements for reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. The significant areas of estimation include determining the allowance for doubtful accounts, the estimated lives and recoverability of property and equipment, and intangible assets, the inputs used in the valuation of goodwill and intangible assets in connection with our impairment tests, the inputs used in the fair value of equity based awards as well as the values ascribed to assets acquired and liabilities assumed in the business combination. Restricted Cash As of December 31, 2020, our total cash balance was $5,277,000, consisting of available cash of $5,058,000, current restricted cash of $158,000, and $61,000 in long-term restricted cash. The long-term restricted cash is included in our other assets on our consolidated balance sheet. The restricted cash pertains to two letters of credit that serve as the security deposit for our leased office space in Munich, Germany and our leased office space in Los Altos, California (as discussed in Note 16 - Commitments and Contingencies ), and is secured by an equal amount of cash pledged as collateral, and such cash is held in a restricted bank account. As of February 28, 2021, the lease and the letter of credit ($158,000) for the Los Altos office space expired. Allowance for Doubtful Accounts We perform ongoing credit evaluations of our customers. We record an allowance for doubtful accounts based on specifically identified amounts that are believed to be uncollectible. We also record additional allowances based on our aged receivables, which are determined based on historical experience and an assessment of the general financial conditions affecting our customer base. If our actual collections experience changes, revisions to our allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. We do not obtain collateral from our customers to secure accounts receivable. The allowance for doubtful accounts was $182,000 and $19,000 at December 31, 2020 and 2019, respectively. Inventory Inventory consists of finished goods and was determined using average costs and was stated at the lower of cost or net realizable value. The Company periodically performs analyses to identify obsolete or slow-moving inventory, and as of December 31, 2020, the Company has recorded an reserve for obsolescence of $193,000. There was no corresponding reserve for 2019. Fair Value of Financial Instruments The Company considers its cash, accounts receivable, accounts payable and debt obligations to meet the definition of financial instruments. The carrying amount of cash, accounts receivable and accounts payable approximated their fair value due to the short maturities of these instruments. The carrying amounts of our debt obligations (see Note 10 - Debt ) approximate their fair values, which are based on borrowing rates that are available to the Company for loans with similar terms, collateral, and maturity. The Company measures fair value as required by Accounting Standards Codification (“ASC”) Topic 820 “Fair Value Measurements and Disclosures” (“ASC Topic 820”). ASC Topic 820 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. ASC Topic 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, there exists a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: • Level 1 - unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date. • Level 2 - inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. • Level 3 - unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606. The Company recognizes revenue using the five-step model as prescribed by Topic 606: • Identification of the contract, or contracts, with a customer; • Identification of the distinct performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when or as the Company satisfies a performance obligation. Oblong’s (formerly Glowpoint) managed videoconferencing services are offered to our customers on either a usage basis or on a subscription. Our network services are offered to our customers on a subscription basis. Revenue for these services is generally recognized on a monthly basis as services are performed. Revenue related to professional services is recognized at the time the services are performed. The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments are deferred on our consolidated balance sheet and amortized over the expected life of the customer contract. Deferred revenue as of December 31, 2020 totaled $27,000 as certain performance obligations were not satisfied as of this date. During the year ended December 31, 2020, the Company recorded $21,000 of revenue that was included in deferred revenue as of December 31, 2019. During the year ended December 31, 2019, the Company recorded $32,000 of revenue that was included in deferred revenue as of December 31, 2018. Oblong Industries’ visual collaboration products are composed of hardware and embedded software sold as a complete package, and generally include installation and maintenance services. Revenue for hardware and software is recognized upon shipment to the customer. Installation revenue is recognized upon completion of installation, which also triggers the beginning of recognition of revenue for maintenance services which range from one to three years. Revenue is recognized over time for maintenance services. Professional services are contracts with specific customers for software development, visual design, interaction design, engineering, and project support. These contracts vary in length, and revenue is recognized over time as services are rendered. Licensing agreements are for the Company’s core technology platform, g-speak, and are generally one year in length. Revenue for these services is recognized ratably over the service period. Upon adoption of Topic 606, Oblong Industries was not required to adjust its revenue recognition methodology, as recognition was deemed to be in-line with the five-step model. Deferred revenue as of December 31, 2020 totaled $1,696,000 as certain performance obligations were not satisfied as of this date. During the year ended December 31, 2020, the Company recorded $978,000 of revenue that was included in deferred revenue as of December 31, 2019. During the three months ended December 31, 2019, the Company recorded $352,000 of revenue that was included in deferred revenue as of the date of the merger. The Company disaggregates its revenue by geographic region. See Note 15 - Segment Reporting for more information. Taxes Billed to Customers and Remitted to Taxing Authorities We recognize taxes billed to customers in revenue and taxes remitted to taxing authorities in our cost of revenue. For the years ended December 31, 2020 and 2019, we included taxes of $313,000 and $390,000, respectively, in revenue and we included taxes of $328,000 and $390,000, respectively, in cost of revenue. Impairment of Long-Lived Assets, Goodwill and Intangible Assets The Company assesses the impairment of long-lived assets used in operations, primarily fixed assets and purchased intangible assets subject to amortization when events and circumstances indicate that the carrying value of the assets might not be recoverable. For purposes of evaluating the recoverability of fixed assets and amortizing intangible assets, the undiscounted cash flows estimated to be generated by those assets are compared to the carrying amounts of those assets. If and when the carrying values of the assets exceed the undiscounted cash flow, then the related assets will be written down to fair value. For the years ended December 31, 2020 and 2019, the Company recorded asset impairment charges on property and equipment of $144,000 and $63,000, which pertained primarily to assets no longer used in the business. During the year ended December 31, 2020, the Company disposed of fixed assets of $3,438,000, and the corresponding accumulated depreciation of $3,287,000, which resulted in a loss on disposal of $151,000. There were no impairments to purchased intangible assets for the years ended December 31, 2020 and 2019. For the year ended December 31, 2020, the Company recorded aggregate impairment charges of $465,000 on two right-of-use assets. See Note 16 - Commitments and Contingencies for further discussion. There were no impairments to right-of-use assets for the year ended December 31, 2019. Goodwill is not amortized but is subject to periodic testing for impairment in accordance with ASC Topic 350 “ Intangibles - Goodwill and Other - Testing Indefinite-Lived Intangible Assets for Impairment” (“ASC Topic 350”). During the years ended December 31, 2020 and 2019, the Company recorded impairment charges on goodwill of $541,000 and $2,254,000, respectively. See Note 7 - Goodwill and Note 8 - Intangible Assets ) for further discussion. Concentration of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, and trade accounts receivable. We place our cash primarily in commercial checking accounts. Commercial bank balances may from time to time exceed federal insurance limits. Property and Equipment Property and equipment are stated at cost and are depreciated over the estimated useful lives of the related assets, which range from three Income Taxes We use the asset and liability method to determine our income tax expense or benefit. Deferred tax assets and liabilities are computed based on temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that are expected to be in effect when the differences are expected to be recovered or settled. Any resulting net deferred tax assets are evaluated for recoverability and, accordingly, a valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax asset will not be realized. Stock-based Compensation Stock-based awards have been accounted for as required by ASC Topic 718 “Compensation – Stock Compensation” (“ASC Topic 718”). Under ASC Topic 718 stock-based awards are valued at fair value on the date of grant, and that fair value is recognized over the requisite service period. The Company accounts for forfeitures when they occur. Research and Development Research and development expenses include internal and external costs related to developing new service offerings and features and enhancements to our existing services. Treasury Stock Purchases and sales of treasury stock are accounted for using the cost method. Under this method, shares acquired are recorded at the acquisition price directly to the treasury stock account. Upon sale, the treasury stock account is reduced by the original acquisition price of the shares and any difference is recorded in additional paid in capital, on a first-in first-out basis. The Company does not recognize a gain or loss to income from the purchase and sale of treasury stock. Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Credit Losses In June 2016 the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” which was subsequently amended in February 2020 by ASU 2020-02, “Financial Instruments - Credit Losses (Topic 326) and Leases (Topic 842).” The amendments introduce an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. The update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact the new guidance will have on its consolidated financial statements.

Liquidity and Going Concern	Dec. 31, 2020
Accounting Policies [Abstract]
Liquidity and Going Concern	Liquidity and Going Concern As of December 31, 2020, we had $5,277,000 of cash and $2,417,000 of total obligations under the MidFirst Bank Loan (the “PPP Loan”) under the Paycheck Protection Program (PPP) contained within the Coronavirus Aid, Relief, and Economic Security (CARES) Act (see Note 10 - Debt ). Our capital requirements in the future will continue to depend on numerous factors, including the timing and amount of revenue for the combined organization, customer renewal rates and the timing of collection of outstanding accounts receivable, in each case particularly as it relates to the combined organization’s major customers, the expense to deliver services, expense for sales and marketing, expense for research and development, capital expenditures, the cost involved in protecting intellectual property rights, the amount of forgiveness of the PPP Loan, if any, and the debt service obligations under the PPP Loan. While our acquisition of Oblong Industries provides additional revenues to the Company, the cost to further develop and commercialize Oblong Industries’ product offerings is expected to exceed its revenues for the foreseeable future. We expect to continue to invest in product development and sales and marketing expenses with the goal of growing the Company’s revenue in the future. The Company believes that, based on the combined organization’s current projection of revenue, expenses, capital expenditures, debt service obligations, and cash flows, it will not have sufficient resources to fund its operations for the next twelve months following the filing of this Report. We believe additional capital will be required to fund operations and provide growth capital including investments in technology, product development and sales and marketing. To access capital to fund operations or provide growth capital, we will need to raise capital in one or more debt and/or equity offerings. There can be no assurance that we will be successful in raising necessary capital or that any such offering will be on terms acceptable to the Company. If we are unable to raise additional capital that may be needed on terms acceptable to us, it could have a material adverse effect on the Company. The factors discussed above raise substantial doubt as to our ability to continue as a going concern. The accompanying consolidated financial statements do not include any adjustments that might result from these uncertainties.

Oblong Industries Acquisition

Oblong Industries Acquisition	12 Months Ended
Oblong Industries Acquisition	Dec. 31, 2020
Business Combinations [Abstract]
Oblong Industries Acquisition	Oblong Industries Acquisition On October 1, 2019, the Company closed its acquisition of Oblong Industries, Inc., a Delaware corporation (“Oblong Industries” and, such transaction, the “Acquisition”). The Acquisition was consummated through the merger of Glowpoint Merger Sub II, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (the “Merger Sub”), with and into Oblong Industries on the Closing Date, with Oblong Industries continuing as the surviving corporation and as a wholly-owned subsidiary of the Company. On the Closing Date, (i) the shares of common and preferred stock of Oblong Industries issued and outstanding immediately prior to the effective time of the Acquisition were converted into an aggregate of 1,686,659 shares of the Company’s 6.0% Series D Convertible Preferred Stock, par value $0.0001 per share (the “Series D Preferred Stock”); (ii) all options to purchase shares of Oblong’s common stock held by previously terminated employees of Oblong Industries were assumed by the Company and deemed, in the aggregate, to constitute options to acquire a total of 107,845 shares of the Company’s common stock, par value $0.0001 per share (“common stock”), at a volume weighted average exercise price of $4.92 per share and a remaining exercise period of one year; and (iii) all options to purchase shares of Oblong Industries’ common stock held by existing employees of Oblong were canceled and exchanged for an aggregate of 49,967 restricted shares of Series D Preferred Stock (“Restricted Series D Preferred Stock”), which are subject to vesting over a two-year period following the Closing Date. Each share of Series D Preferred Stock is automatically convertible into a number of shares of Common Stock equal to the accrued value of the share (initially $28.50), plus any accrued dividends thereon, divided by the Conversion Price (initially $2.85 per share, subject to specified adjustments) upon the completion of both i) approval of such conversion by the Company’s stockholders (which occurred on December 19, 2019) and (ii) the receipt of all required authorizations and approval of a new listing application for the combined organization from the NYSE American. Upon such conversion, the Series D Preferred Stock (including shares of Restricted Series D Preferred Stock) will convert into an aggregate of 17,349,010 shares of common stock. Following their conversion to common stock, shares of Restricted Series D Preferred Stock will remain subject to their vesting conditions. Subsequent to the date of this Annual Report on Form 10-K, the company transferred the listing of its common stock from the NYSE American to the Nasdaq Capital Market. Upon this transfer, all of the Series D Preferred Stock, including the Restricted Series D Stock, was converted into shares of the Company’s common stock. Please refer to Note 20 - Subsequent Events for further discussion of the transfer and the conversion. The Acquisition was accounted for in accordance with FASB Accounting Standards Codification Topic 805 “Business Combinations” (“ASC 805”) as a business combination, which requires an allocation of the purchase price of an acquired entity to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The purchase price and the fair value of the assets acquired and liabilities assumed were based on management estimates and values with assistance from an outside appraisal. Pursuant to ASC 805, the purchase price of $18,862,000 was measured as the fair value of the consideration exchanged in the Acquisition as follows: Series D Preferred Stock (1,686,659 shares at $11.15 per share) $ 18,811,000 Value of common stock options issued (107,845 at $0.47 per option) $ 51,000 Total purchase price $ 18,862,000 The value per share of the Series D Preferred Stock was determined using an equity allocation method using the Company’s publicly traded common stock as the basis, with use of an option pricing model for determination of the value per share of the Series D Preferred Stock in the event conversion to common stock does not occur. On October 1, 2019, the closing sale price of our common stock was $1.00 per share as reported on the NYSE American. The value of the 107,845 common stock options was determined using the Black-Scholes method, with the following weighted-average assumptions: (i) exercise price of $4.92, (ii) risk-free interest rate of 1.5%, (iii) expected volatility of 217% and (iv) expected term of one year. The value of the Restricted Series D Preferred Stock was not included in the purchase price given the vesting requirements post combination. Therefore, the Company recorded stock-based compensation expense in the post combination period over the vesting period of these awards. Based on the purchase price allocation, the following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the Closing Date (in thousands): Cash $ 2,194 Accounts receivable 1,962 Prepaid expenses and other current assets 719 Inventory 1,835 Property and equipment 1,221 Operating lease, right-of-use assets 3,376 Trade names 2,410 Distributor relationships 310 Developed technology 10,060 Other assets 194 Total assets acquired at fair value $ 24,281 Accounts payable $ (296) Operating lease liabilities (3,578) Deferred revenue (2,231) Debt (5,509) Other liabilities (1,171) Total liabilities assumed $ (12,785) Net assets acquired $ 11,496 The purchase price exceeded the fair value of the net assets acquired by 7,367,000, which was recorded as goodwill. The accompanying consolidated financial statements do not include any revenues or expenses related to the Oblong Industries business on or prior to October 1, 2019 (the Closing Date of the Acquisition). A total of $468,000 of acquisition costs were expensed and included in General and Administrative expenses in the accompanying Statement of Operations for the year ended December 31, 2019. The preliminary allocation of the purchase price was based upon a valuation for which the estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The final allocation price could differ materially from the preliminary allocation. Any subsequent changes to the purchase price allocation that result in material changes to the Company’s consolidated financial results will be adjusted accordingly. The consolidated statement of operations for the year ended December 31, 2019 includes $3,167,000 of revenue and net loss of $3,360,000 related to Oblong Industries for the period from October 1, 2019 through December 31, 2019. The Company's unaudited pro forma results for the year ended December 31, 2019 is summarized in the table below, assuming the Acquisition had occurred on January 1, 2019 (in thousands). These unaudited pro forma results have been prepared for comparative purposes only and do not purport to be indicative of the results of operations which would have actually resulted had the acquisition occurred on January 1, 2019, nor to be indicative of future results of operations. These pro forma results include pro forma adjustments of $1,393,000 for the year ended December 31, 2019 related to the incremental amortization of Oblong Industries’ intangible assets recorded in connection with the Acquisition.

Goodwill	Goodwill As of December 31, 2020 and 2019, goodwill was $7,367,000 and $7,908,000, respectively. As of December 31, 2020, goodwill was comprised of $7,367,000 recorded in connection with the October 1, 2019 acquisition of Oblong Industries. We test goodwill for impairment on an annual basis on September 30 of each year, or more frequently if events occur or circumstances change indicating that the fair value of the goodwill may be below its carrying amount. Following the Acquisition of Oblong Industries, the Company operated two reporting units, Oblong (formerly Glowpoint) and Oblong Industries. During the year ended December 31, 2020, we considered the novel Coronavirus (COVID-19) pandemic and resulting declines in certain of the Company’s revenue to be a triggering event for an interim goodwill impairment test for both reporting units as of March 31, 2020. To determine the fair value of each reporting unit for the goodwill impairment tests, we used a weighted average of the discounted cash flow method and a market-based method (comparing the Company’s equity and analyzing multiples of revenue for comparable companies). For the Oblong Industries reporting unit, the fair value of the reporting unit exceeded its carrying amount, as of both testing dates, therefore no impairment charge was required for the year ended December 31, 2020. For the Oblong (formerly Glowpoint) reporting unit, we recorded an impairment charge on goodwill of $541,000 at March 31, 2020, as the carrying amount of the reporting unit exceeded its fair value on the test date. This charge is recognized as “Impairment Charges” on our consolidated Statements of Operations, and reduced goodwill for the Oblong. reporting unit to zero. The activity in goodwill during the years ended December 31, 2020 and 2019 is shown in the following table ($ in thousands): Goodwill Oblong Oblong Industries Total Balance January 1, 2019 $ 2,795 $ — $ 2,795 Acquisition — 7,367 7,367 Impairment (2,254) — (2,254) Balance December 31, 2019 541 7,367 7,908 Impairment (541) — (541) Balance December 31, 2020 $ — $ 7,367 $ 7,367 In the event we experience future declines in our revenue, cash flows and/or stock price, this may give rise to a triggering event that may require the Company to record additional impairment charges on goodwill in the future.

The SVB Loan Agreement provided for a term loan facility of approximately $5,247,000, and a discount of $362,000, for a total liability of $5,609,000 (the “SVB Loan”), all of which was outstanding at December 31, 2019. The Loan had a maturity date of March 1, 2022 with monthly payments of $291,500 (plus accrued and unpaid interest) to begin on October 1, 2020. The SVB Loan accrued interest at a rate equal to the Prime Rate plus 425 basis points (for a total of 7.50% as of September 30, 2020). In connection with its execution of the amended SVB Loan Agreement on October 1, 2019, the Company issued a warrant to SVB that entitles SVB to purchase 72,394 shares of the Company’s common stock at an exercise price of $0.01 per share (the “SVB Warrant”). The SVB Warrant has a ten (10) year term. The fair value of the SVB Warrant was recorded to additional paid-in capital and was determined to be $72,000 using the Black-Scholes model. The debt discount associated with the SVB Loan was being amortized to interest expense using the effective interest method over the term of the debt. During the year ended December 31, 2020, the Company amortized $83,000 of the debt discount, which is recorded in “Interest and other expense, Net” on our Consolidated Statements of Operations, and $47,000 of the discount was forgiven in the Satisfaction Agreement discussed below. On October 22, 2020, the Company entered into an agreement (the “ S atisfaction Agreement”) with certain of its subsidiaries, Oblong Industries, Inc. and GP Communications, LLC (the “Guarantors”), and SVB as lender, pursuant to which SVB agreed to accept a one-time cash payment of $2,500,000 (the “Satisfaction Payment”) in satisfaction of the Company’s outstanding payment obligations under the SVB Loan Agreement, effective immediately, subject to certain terms and conditions. SVB also agreed to release the security interests and other liens previously granted to or held by SVB as security for the Company’s obligations under the SVB Loan Agreement, as well as the Guarantors’ guarantees thereof. The Company made the Satisfaction Payment on October 22, 2020. The remaining balance of $3,063,000, net of discount, as well as $54,000 of accrued interest was forgiven and recorded as a “Gain on Extinguishment of Debt” on our Consolidated Statements of Operations. As of December 31, 2020, the Company has no outstanding obligations under the SVB Loan Agreement. Paycheck Protection Program Loan On April 10, 2020 (the “Origination Date”), the Company received $2,417,000 in aggregate loan proceeds (the “PPP Loan”) from MidFirst Bank (the “Lender”) pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief, and Economic Security (CARES) Act. The PPP Loan is evidenced by a Promissory Note (the “Note”), dated April 10, 2020, by and between the Company and the Lender. Subject to the terms of the Note, the PPP Loan bears interest at a fixed rate of one percent (1.0%) per annum. Under the terms of the Note, payments of principal and interest are deferred for six months from the origination date. Following the deferral period, the Company will be required to make payments of principal plus interest accrued under the PPP Loan to the Lender in 18 monthly installments based upon an amortization schedule to be determined by the Lender based on the principal balance of the Note outstanding following the deferral period and taking into consideration any portion of the PPP Loan that is forgiven prior to that time. The PPP Loan is unsecured and guaranteed by the U.S. Small Business Administration. The Paycheck Protection Program provides for forgiveness of up to the full amount borrowed as long as the Company uses the loan proceeds during the 24-week period following disbursement for eligible purposes as described in the CARES Act and related guidance. Under the CARES Act, loan forgiveness is generally available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilities during the 24-week period. The Company used the majority of the proceeds from the PPP Loan to pay expenses during the applicable period that the Company believes were for eligible purposes; certain reductions in Company payroll costs during this period may reduce the amount of the Note eligible for forgiveness. The Company expects to submit an application to the Lender for forgiveness of the PPP Loan in the second quarter of 2021. There is no guarantee that the Company will receive forgiveness for any fixed amount of any PPP Loan principal received by the Company. Under the revised rules for the PPP Loan program, the Company will not have to begin principal and interest payments before the date on which the SBA remits the loan forgiveness amount to the Lender (or notifies the Lender that no loan forgiveness is allowed). Following the decision on forgiveness, the Company will be required to pay the Lender equal monthly payments of principal and interest based on the principal amount outstanding on the PPP Loan, plus interest outstanding at the end of the deferment period, and taking into account any reductions in the principal amount due to forgiveness, if any. Interest accrued during the deferment period will be capitalized as principal. The Company has accounted for the PPP Loan in the same manner as it has for its other loan agreements. Payments that are due within 12 months of balance sheet dates are shown as current liabilities and payments due thereafter are shown as non-current liabilities. We expect our forgiveness application to be processed, and any applicable payments to begin in May 2021. If the Company’s application for forgiveness is approved, the Company will recognize a gain on extinguishment of debt at the time of forgiveness. As of December 31, 2020 the remaining principal balance on the Note is $2,417,000 and $18,000 of interest has been accrued. Future minimum principal payments are as follows (in thousands): Future Minimum Principal Payments PPP Loan 1 2021 $ 2,014 2022 $ 403 $ 2,417 1 Future minimum payments is based on the repayment beginning in May 2021. The Note provides for customary events of default including, among other things, failure to make any payment when due, cross-defaults under any loan documents with the Lender, certain cross-defaults under agreements with third parties, inaccuracy of representations and warranties, events of dissolution or insolvency, certain change of control events, and material adverse changes in the Company’s financial condition. If an event of default occurs, the Lender will have the right to accelerate indebtedness under the PPP Loan and/or pursue other remedies available to the Lender at law or in equity.

Net proceeds were $2,717,000, after deducting issuance costs of $256,000. The Private Placement closed on October 22, 2020. The Warrants have a term of 2 years, are initially exercisable at $4.08 per share and are subject to cashless exercise if, at the time of exercise, the Warrant Shares are not subject to an effective resale registration statement. The Warrants are also subject to adjustment in the event of (i) stock splits and dividends, (ii) subsequent rights offerings, (iii) pro-rata distributions, and (iv) certain fundamental transactions, including but not limited to the sale of the Company, business combinations, and reorganizations.

The number of shares purchased under the Stock Repurchase Program and the timing of any purchases may be based on many factors, including the level of the Company’s available cash, general business conditions, and the pricing of the Common Stock. The Stock Repurchase Program does not obligate the Company to acquire a specific number of shares and may be suspended, modified, or terminated at any time. During the year ended December 31, 2020, the Company did not repurchase any shares of Common Stock. All shares of Common Stock repurchased under the Stock Repurchase Program are recorded as treasury stock. The Stock Repurchase Program does not have an expiration date.

Preferred Stock, Number of Shares, Par Value and Other Disclosures [Abstract]
Preferred Stock	Preferred Stock Our Certificate of Incorporation authorizes the issuance of up to 5,000,000 shares of preferred stock. The following table shows our authorized, issued, and outstanding preferred stock as of December 31, 2020: Authorized Issued and Outstanding 5% Series A-2 Preferred 7,500 45 0% Series C Preferred 1,750 — 0% Series D Preferred 4,000 — 6% Series D Preferred 1,750,000 1,697,958 6% Series E Preferred 175,000 131,579 1,938,250 1,829,582 Series A-2 Preferred Stock Each share of Series A-2 Preferred Stock has a stated value of $7,500 per share (the “A-2 Stated Value”), a liquidation preference equal to the Series A-2 Stated Value, and is convertible at the holder’s election into common stock at a conversion price per share of $16.11 as of December 31, 2020. Therefore, each share of Series A-2 Preferred Stock is convertible into 466 shares of common stock, for an aggregate of 20,950 shares of common stock, as of December 31, 2020. The conversion price is subject to adjustment upon the occurrence of certain events set forth in our Certificate of Incorporation. The Series A-2 Preferred Stock is senior to all outstanding classes of the Company’s equity, has weighted average anti-dilution protection and, effective January 1, 2013, entitled to cumulative dividends at a rate of 5.0% per annum, payable quarterly, based on the Series A-2 Stated Value and payable at the option of the holder in cash or through the issuance of a number of additional shares of Series A-2 Preferred Stock with an aggregate liquidation preference equal to the dividend amount payable on the applicable dividend payment date. As of December 31, 2020 and 2019, the Company has recorded $4,000 and $99,000, respectively, in accrued dividends on the accompanying Consolidated Balance Sheets related to the Series A-2 Preferred Stock outstanding. During the year ended December 31, 2020, $17,000 in dividends were accrued, $13,000 in accrued dividends were paid, and $99,000 in accrued and unpaid dividends were exchanged for 13 additional shares of Series A-2 Preferred Stock. The Company, at its option, may redeem all or a portion of the Series A-2 Preferred Stock in cash at a price per share of $8,250 (equal to $7,500 per share multiplied by 110%) plus all accrued and unpaid dividends. In accordance with ASC Topic 815, we evaluated whether our convertible preferred stock contains provisions that protect holders from declines in our stock price or otherwise could result in modification of the exercise price and/or shares to be issued under the respective preferred stock agreements based on a variable that is not an input to the fair value of a “fixed-for-fixed” option and require a derivative liability. The Company determined no derivative liability is required under ASC Topic 815 with respect to our convertible preferred stock. A contingent beneficial conversion amount is required to be calculated and recognized when and if the adjusted $16.11 conversion price of the Series A-2 Preferred Stock is adjusted to reflect a down round stock issuance that reduces the conversion price below the $11.16 fair value of the common stock on the issuance date of the Series A-2 Preferred Stock. On January 28, 2021, all outstanding shares of the series A-2 Preferred Stock, and accrued dividends, were converted into shares of common stock. Refer to Note 20 - Subsequent Events, for further discussion of the conversion. Series C Preferred Stock On January 25, 2018, the Company closed a registered direct offering of 1,750 shares of its Series C Preferred Stock for total gross proceeds to the Company of $1,750,000. The shares of Series C Preferred Stock were sold at a price equal to their stated value of $1,000 per share and were convertible into shares of the Company’s common stock at a conversion price of $3.00 per share. During the years ended December 31, 2020 and 2019, 475 and 50 shares of Series C Preferred Stock were converted to 158,333 and 16,667 shares of the Company’s common stock, respectively. As of December 31, 2020, no shares of Series C Preferred Stock remain issued and outstanding. Series D Preferred Stock In connection with the Acquisition (see Note 3 - Oblong Industries Acquisition ), the Company issued an aggregate of 1,686,659 shares of Series D Preferred Stock and an aggregate of 49,967 restricted shares of Series D Preferred Stock (“Restricted Series D Preferred Stock”), the latter of which are subject to vesting over a two-year period following the Closing Date of the Acquisition. Each share of Series D Preferred Stock is automatically convertible into a number of shares of the Company’s common stock equal to the accrued value of the share (initially $28.50), plus any accrued dividends thereon, divided by the Conversion Price (initially $2.85 per share, subject to specified adjustments) upon the completion of both (i) approval of such conversion by the Company’s stockholders (which occurred on December 19, 2019); and (ii) the receipt of all required authorizations and approval of a new listing application for the combined organization from the NYSE American or any such other exchange upon which the Company’s securities are then listed for trading. Pursuant to the terms of the Series D Certificate of Designations, each share of Series D Preferred Stock is entitled to receive an annual dividend equal to 6% of its then-existing Accrued Value per annum, commencing on the first anniversary of the issuance of the Series D Preferred Stock (or October 1, 2020). Prior to the first anniversary of the issuance of the Series D Preferred Stock no dividends will accrue on such stock. Dividends are cumulative and accrue daily in arrears. If the Company’s Board of Directors does not declare any applicable dividend payment in cash, the Accrued Value of the Series D Preferred Stock will be increased by the amount of such dividend payment. The undeclared dividends for the Series D Preferred Stock, as of December 31, 2020, were $732,000, and increased the value of the Series D Preferred Stock by such amount. During the years ended December 31, 2020 and 2019, 28,618 and 1,725 of Restricted Series D Preferred Stock were forfeited, respectively, and, in 2020, $8,325 shares of Series D Preferred Stock were surrendered to cover the taxes on vesting shares. As of December 31, 2020, there are 1,647,991 shares of Series D Preferred Stock, and 49,967 shares of Restricted Series D Preferred Stock outstanding. Series E Preferred Stock On October 1, 2019, Oblong entered into a Series E Preferred Stock Purchase Agreement (the “Purchase Agreement”) with the investors party thereto, who, prior to the closing of the Acquisition, were stockholders of Oblong Industries (the “Purchasers”), relating to the offer and sale by the Company in a private placement (the “Offering”) of up to 131,579 shares of its Series E Preferred Stock at a price of $28.50 per share. At an initial closing on October 1, 2019 and a subsequent closing on December 18, 2019, the Company sold a total of 131,579 shares of Series E Preferred Stock for net proceeds of approximately $3,750,000. The 131,579 shares of Series E Preferred Stock issued by the Company in the Series E Financing have an aggregate Accrued Value of $3,750,000 and upon their conversion will convert at a conversion price of $2.85 per share into 1,315,790 common shares. Like the Series D Preferred Stock, each share of Series E Preferred Stock is automatically convertible into common stock upon the receipt of all required authorizations and approval of a new listing application for the combined organization from the NYSE American or any such other exchange upon which the Company’s securities are then listed for trading. Pursuant to the terms of the Series E Certificate of Designations, each share of Series E Preferred Stock is entitled to receive an annual dividend equal to 6.0% of its then-existing Accrued Value per annum, commencing on the first anniversary of the issuance of the Series E Preferred Stock (or October 1, 2020 or December 18, 2020, as applicable). Prior to the first anniversary of the issuance of the Series E Preferred Stock no dividends will accrue on such stock. Dividends are cumulative and accrue daily in arrears. If the Company’s Board of Directors does not declare any applicable dividend payment in cash, the Accrued Value of the Series E Preferred Stock will be increased by the amount of such dividend payment. The undeclared dividends for the Series E Preferred Stock, as of December 31, 2020, were $56,000, and increased the value of the Series E Preferred Stock by such amount. During the years ended December 31, 2020 and 2019 no shares of Series E Preferred Stock were forfeited and 131,579 shares remain outstanding as of December 31, 2020. Subsequent Conversion If the outstanding shares of Series D and Series E Preferred Stock had been converted to common stock as of December 31, 2020, 17,020,100 and 1,315,790 shares of common stock would have been issued for the Series D and Series E Preferred Stock, respectively, which would have increased our outstanding shares of common stock from 7,748,629 to 26,084,519. In 2021 all outstanding shares of the Series D and Series E Preferred Stock, plus the value of the 6.0% dividend, were converted into shares of common stock. Refer to Note 20 - Subsequent Events,

The 2019 Plan is an omnibus equity incentive plan pursuant to which the Company may grant equity and cash incentive awards to certain key service providers of the Company and its subsidiaries. The 2019 Plan replaces the Glowpoint, Inc. 2014 Equity Incentive Plan (the “Prior Plan”), which was adopted by the Company’s Board of Directors on April 22, 2014, and subsequently approved by the Company’s stockholders. Following approval of the 2019 Plan, the Company terminated the Prior Plan and may no longer make grants under the Prior Plan; however, any outstanding equity awards granted under the Prior Plan will continue to be governed by the terms of the Prior Plan. The maximum number of shares of the Company’s Common Stock initially reserved and available for issuance under the 2019 Plan was equal to the sum of (i) 2,600,000 shares the Company’s Common Stock and (ii) 421,000 shares of the Company’s Common Stock remaining available for issuance under the Prior Plan at the time of its termination.

Net Loss Per Share

Net Loss Per Share	Dec. 31, 2020
Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares of common stock outstanding does not include any potentially dilutive securities or any unvested restricted shares of common stock. These unvested restricted shares, although classified as issued and outstanding at December 31, 2020 and December 31, 2019, are considered contingently returnable until the restrictions lapse and will not be included in the basic net loss per share calculation until the shares are vested. Unvested shares of our restricted stock do not contain non-forfeitable rights to dividends and dividend equivalents. Vested RSUs (for which shares of common stock have not yet been delivered) are included in the calculations of basic net loss per share. Unvested RSUs are not included in calculations of basic net loss per share, as they are not considered issued and outstanding at time of grant. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, preferred stock, RSUs, and unvested restricted stock awards, to the extent they are dilutive. For the year ended December 31, 2020, all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive (due to the net losses). The following table sets forth the computation of the Company’s basic and diluted net loss per share (in thousands, except per share data): Year Ended December 31, Numerator: 2020 2019 Net loss $ (7,421) $ (7,761) Less: preferred stock dividends 17 27 Less: undeclared dividends $ 788 $ — Net loss attributable to common stockholders $ (8,226) $ (7,788) Denominator: Weighted-average number of shares of common stock for basic net loss per share 5,547 5,108 Basic and diluted net loss per share $ (1.48) $ (1.52) The weighted-average number of shares for the years ended December 31, 2020 and 2019 includes 28,904 and 28,904 shares, respectively, of vested RSUs, as discussed in Note 13 - Stock Based Compensation . The following table represents the potential shares that were excluded from the computation of weighted-average number of shares of common stock in computing the diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Year Ended December 31, 2020 2019 Unvested restricted stock units — 23,334 Outstanding stock options 107,500 215,345 Unvested restricted stock awards 627 627 Shares of common stock issuable upon conversion of Series A-2 preferred stock 18,161 10,978 Shares of common stock issuable upon conversion of Series C preferred stock — 158,333 Shares of common stock issuable upon conversion of Series D preferred stock 17,020,100 17,349,010 Shares of common stock issuable upon conversion of Series E preferred stock 1,315,790 1,315,790 Warrants 1,146,500 72,394

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Prior to the acquisition of Oblong Industries on October 1, 2019, the Company operated in one segment. The businesses of Oblong (formerly Glowpoint) and Oblong Industries were managed separately during the fourth quarter of 2019 and the year ended December 31, 2020, and involve different products and services. Accordingly, the Company currently operates in two segments: (1) the Oblong business which mainly consists of managed services for video collaboration and network applications; and (2) the Oblong Industries business which consists of products and services for visual collaboration technologies. Because the closing of the acquisition of Oblong Industries occurred on October 1, 2019, the Company’s consolidated financial statements as of and for the year ended December 31, 2019 included in this Report only reflect Oblong Industries’ financial results for the fourth quarter of 2019, as compared to full year results for the year ended December 31, 2020. Certain information concerning the Company’s segments for the years ended December 31, 2020 and 2019 is presented in the following tables (in thousands): For the Year Ended December 31, 2020 Oblong (formerly Glowpoint) Oblong Industries Corporate Total Revenue $ 6,227 $ 9,106 $ — $ 15,333 Cost of revenues 3,789 3,491 — 7,280 Gross profit $ 2,438 $ 5,615 $ — $ 8,053 Gross profit % 39.2 % 61.7 % — % 52.5 % Allocated operating expenses $ 1,479 $ 9,913 $ — $ 11,392 Unallocated operating expenses — — 6,725 6,725 Total operating expenses $ 1,479 $ 9,913 $ 6,725 $ 18,117 Income (loss) from operations $ 959 $ (4,298) $ (6,725) $ (10,064) Interest and other income (expense), net (19) 2,765 — 2,746 Income (loss) before income taxes. $ 940 $ (1,533) $ (6,725) $ (7,318) Income tax expense $ 50 $ 53 $ — $ 103 Net income (loss) $ 890 $ (1,586) $ (6,725) $ (7,421) As of December 31, 2020 Total assets $ 6,494 $ 22,649 $ — $ 29,143 For the Year Ended December 31, 2019 Oblong (formerly Glowpoint) Oblong Industries Corporate Total Revenue $ 9,660 $ 3,167 $ — $ 12,827 Cost of revenues 6,269 1,158 — 7,427 Gross profit $ 3,391 $ 2,009 $ — $ 5,400 Gross profit % 35.1 % 63.4 % — % 42.1 % Allocated operating expenses $ 6,835 $ 5,183 $ — $ 12,018 Unallocated operating expenses — — 956 956 Total operating expenses $ 6,835 $ 5,183 $ 956 $ 12,974 Loss from operations $ (3,444) $ (3,173) $ (956) $ (7,574) Interest and other expense, net — — (187) (187) Loss before income taxes $ (3,444) $ (3,173) $ (1,143) $ (7,761) Income tax expense $ — $ — $ — $ — Net loss $ (3,444) $ (3,173) $ (1,143) $ (7,761) As of December 31, 2019 Total assets $ 5,942 $ 28,967 $ — $ 34,909 Unallocated operating expenses include costs for the year ending December 31, 2020 that are not specific to a particular segment but are general to the group; included are expenses incurred for administrative and accounting staff, general liability and other insurance, professional fees and other similar corporate expenses.

Commitments and Contingencies	12 Months Ended
Commitments and Contingencies	Dec. 31, 2020
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Operating Leases We lease three facilities in Los Angeles, California, one facility in Boston, Massachusetts, one facility in Dallas, Texas, and one facility in Munich Germany, all providing office space. We also lease space in City of Industry, California, providing warehouse space. These leases expire between 2022 and 2023. During 2020, and through the date of this filing, we exited leases in Herndon, Virginia; Atlanta, Georgia; Houston, Texas; Los Altos, California; London, England, and a warehouse space in Los Angeles, California. Although subject to COVID restrictions, we currently occupy two of the facilities in Los Angeles and the warehouse space in City of Industry; we have subleases in place for the third Los Angeles property, the Dallas property, and the Boston property. The Munich property is not in use and the Company is considering its options with this lease. Lease expenses, net of common charges and sublet proceeds, for the years ended December 31, 2020 and 2019 were $997,000 and $580,000, respectively. The 2019 lease expense consisted of twelve months of lease expense for Oblong (formerly Glowpoint) and three months of lease expense for Oblong Industries. The 2020 expenses consisted of twelve months of lease expense for Oblong Industries, and three months of lease expense for Oblong. The Company primarily leases facilities for office and data center space under non-cancellable operating leases for its U.S. and international locations that expire at various dates through 2023. For leases with a term greater than 12 months, the Company recognizes a right-of-use asset and a lease liability based on the present value of lease payments over the lease term. Variable lease payments are not included in the lease payments to measure the lease liability and are expensed as incurred. The Company’s leases have remaining terms of one As the Company's leases do not provide a readily determinable implicit rate, the Company uses the incremental borrowing rate at lease commencement, which was determined using a portfolio approach, based on the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. Operating lease expense is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recognized on the balance sheet and the expense for these short-term leases is recognized on a straight-line basis over the lease term. Common area maintenance fees (or CAMs) and other charges related to these leases continue to be expensed as incurred. The following provides balance sheet information related to leases as of December 31, 2020 and 2019 (in thousands): Year Ended December 31, 2020 2019 Assets Operating lease, right-of-use asset, net $ 903 $ 3,117 Liabilities Current portion of operating lease liabilities $ 830 $ 1,294 Operating lease liabilities, net of current portion 602 2,020 Total operating lease liabilities $ 1,432 $ 3,314 The following table summarizes the future undiscounted cash payments reconciled to the lease liability (in thousands): Year Ending December 31, 2021 $ 901 2022 514 2023 116 Total lease payments $ 1,531 Effect of discounting (99) Total lease liability $ 1,432 During the year ended December 31, 2020, we entered into one new operating lease, terminated six operating leases, and took impairment losses on the right-of-use assets on two of our operating leases. The following table provides a reconciliation of activity for our right of use assets and lease liabilities (in thousands): Right-of-Use Asset Operating Lease Liability Balance at December 31, 2019 $ 3,117 $ 3,314 Additions $ 116 $ 116 Terminations and Modifications $ (864) $ (860) Amortizations and Reductions $ (1,001) $ (1,138) Impairment Charges $ (465) $ — Balance at December 31, 2020 $ 903 $ 1,432 The ROU assets and lease liabilities are recorded on the Company’s consolidated balance sheets as of December 31, 2020 and December 31, 2019. During the year ended December 31, 2020, non-cash immaterial out-of-period adjustments of approximately $195,000 were recorded to reduce the right of use asset and lease liability. These adjustments related to an error in the calculation of these amounts, in connection with the Oblong Acquisition. During the year ended December 31, 2020, the Company entered into one new lease, in City of Industry, CA, for warehouse space. The new lease commenced on September 1, 2020 and has a term of 18 months. The new lease resulted in an addition to ROU Assets, and corresponding increase to lease liability, of $116,000. During the year ended December 31, 2020, the Company exited six of its leases, one in Denver, one in New York, one in London, one in Atlanta, one in Los Angeles, and one in Virginia. The Denver lease was exited in the first quarter of 2020, the New York and London leases were exited in the second quarter of 2020, and the Atlanta lease was exited in the third quarter of 2020 when the Company elected not to renew the leases. The Los Angeles lease was exited in third quarter of 2020, and the Virginia lease was exited in the fourth quarter of 2020, when the Company negotiated early terminations of the leases. These lease exits resulted in the reduction of ROU assets and the reduction of lease liability. The Denver ROU asset was fully amortized, and the lease liability had been fully paid, as of the date of exit resulting in a net effect of zero on the ROU asset and operating lease liability on the Company’s consolidated balance sheet during the first quarter of 2020. The New York ROU asset was fully amortized, and the lease liability had been fully paid, as of the date of exit resulting in a net effect of zero on the ROU asset and operating lease liability on the Company’s consolidated balance sheet during the first quarter of 2020. The London lease expired in April 2020 and the Company elected not to renew the lease. The Company had originally planned to renew the London Lease, and, pursuant to ASC 842, had recorded additional operating lease liability and ROU asset value. Upon the exit of the London Lease, the Company recorded a disposal of ROU asset value of $214,000 and corresponding reduction of operating lease liability of $197,000 on the Company’s consolidated balance sheet during the first quarter of 2020. On April 24, 2020, the Company signed an amendment to the lease on our Los Angeles warehouse in order to exit the lease early. The original termination date of the lease was the end of May 2022 and we exited the lease at the end of August 2020. Upon the exit of the LA Warehouse Lease, the Company recorded a disposal of ROU asset value of $317,000 and corresponding reduction of operating lease liability of $333,000 of lease liability on the Company’s consolidated balance sheet during the second quarter of 2020. In addition, in exchange for the early termination, the Company forfeited its security deposit of $26,000. On July 31, 2020, the Company entered into a termination agreement related to our lease in Atlanta, upon the expiration of the lease term. The Company had originally planned to renew the Atlanta Lease, and, pursuant to ASC 842, had recorded additional operating lease liability and ROU asset value. Upon exit of the Atlanta lease, the Company recorded a disposal of ROU asset value of $17,000, and a corresponding reduction of lease liability of $20,000, on the Company’s consolidated balance sheet during the third quarter of 2020. On November 30, 2020, the Company entered into a termination agreement, related to our lease in Virginia, in exchange for a cancellation fee of $45,000 and the forfeiture of our $18,000 security deposit. The original term of the lease was set to expire in September 2022. Upon exit of the Virginia lease, the Company recorded a disposal of ROU asset value of $120,000, and a corresponding reduction of lease liability of $137,000, on the Company’s consolidated balance sheet during the fourth quarter of 2020. During 2020, the Company subleased its office space in Dallas and Los Altos, a portion of its office space in Boston, and in December 2020, we subleased one of the units of our LA office space. The sublease terms all mirror the remaining terms of their respective leases, and all subleases are in good standing. During the year ended December 31, 2020, the Company recorded an offset of approximately $374,000 to our rent and occupancy expenses from the proceeds of these subleases. On December 31, 2020, the Company determined it was not going to be able to sublet the remainder of the Boston property, or any of the Munich property, and impaired the ROU asset value of these leases. The Company recorded impairment charges of $195,000 and $270,000 on the ROU assets of the Boston and Munich leases, respectively, and included these amounts in impairment expense in the accompanying consolidated statement of operations for the year ended December 31, 2020. COVID-19 On March 11, 2020, the World Health Organization announced that infections of the novel Coronavirus (COVID-19) had become pandemic, and on March 13, the U.S. President announced a National Emergency relating to the disease. There is a possibility of continued widespread infection in the United States and abroad, with the potential for catastrophic impact. National, state and local authorities have required or recommended social distancing and imposed or are considering quarantine and isolation measures on large portions of the population, including mandatory business closures. These measures, while intended to protect human life, are expected to have serious adverse impacts on domestic and foreign economies of uncertain severity and duration. Some economists are predicting the United States will soon enter a recession. The sweeping nature of the coronavirus pandemic makes it extremely difficult to predict how the Company’s business and operations will be affected in the longer run, but we expect that it may materially affect our business, financial condition and results of operations. The extent to which the coronavirus impacts our results will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others. Moreover, the coronavirus outbreak has begun to have indeterminable adverse effects on general commercial activity and the world economy, and our business and results of operations could be adversely

The change in valuation allowance for the year ended December 31, 2020 is an decrease of $4,005,000 principally due to the reduction of NOLs due to Section 382 limitations. The change in valuation allowance for the year ended December 31, 2019 was an increase of $25,040,000. We and our subsidiary file federal and state tax returns on a consolidated basis. On October 1, 2019 Oblong, Inc. acquired the stock of Oblong Industries Inc. that resulted in Oblong Industries Inc.'s shareholders now owning 75% of Oblong, Inc. Therefore, an “ownership change” occurred on this date (as defined under Section 382 of the Internal Revenue Code of 1986, as amended), which places an annual limitation on the utilization of the net operating loss (“NOL”) carryforwards accumulated before the ownership change. If additional ownership changes occur in the future, the use of the net operating loss carryforwards could be subject to further limitation. As a result of this annual limitation and the limited carryforward life of the accumulated NOLs, we determined that the ownership change resulted in the permanent loss of approximately $30,880,000 of tax NOL carryforwards. At December 31, 2019, we had federal net operating loss carryforwards of $108,497,000 available to offset future federal taxable income which expire in various amounts from 2020 through 2037. At December 31, 2020, we had federal net operating loss carryforwards of $110,401,000 available to offset future federal taxable income which expire in various amounts from 2020 through 2037. Of this amount, 5,928,000 is subject to annual Section 382 limitations. As of December 31, 2020 and 2019, the Company also has various state net operating loss carryforwards of $94,223,000 and $141,210,000, respectively. The determination of the state net operating loss carryforwards is dependent upon apportionment percentages and state laws that can change, from year to year and impact the amount of such carryforwards. There were no significant matters determined to be unrecognized tax benefits taken or expected to be taken in a tax return, in accordance with ASC Topic 740 “ Income Taxes ” (“ASC 740”), which clarifies the accounting for uncertainty in income taxes recognized in the financial statements, that have been recorded on the Company’s consolidated financial statements for the years ended December 31, 2020 and 2019. The Company does not anticipate a material change to unrecognized tax benefits in the next twelve months. Additionally, ASC 740 provides guidance on the recognition of interest and penalties related to unrecognized tax benefits. There were no interest or penalties related to income taxes that have been accrued or recognized as of and for the years ended December 31, 2020 and 2019. The federal and state tax returns for the 2017 and subsequent years are currently open to examination.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Oblong and our 100%-owned subsidiaries (i) GP Communications, LLC (“GP Communications”), whose business function is to provide interstate telecommunications services for regulatory purposes, (ii) Oblong Industries, Inc., and (iii) the following subsidiaries of Oblong Industries: Oblong Industries Europe, S.L. and Oblong Europe Limited. All inter-company balances and transactions have been eliminated in consolidation. The U.S. Dollar is the functional currency for all subsidiaries.
Segments	Segments Prior to the acquisition of Oblong Industries on October 1, 2019, the Company operated in one segment. Effective October 1, 2019, the former businesses of Glowpoint, Inc. (now Oblong, Inc.) and Oblong Industries were managed separately and involve different products and services. Accordingly, the Company currently operates in two segments: 1) the Oblong, Inc. (formerly Glowpoint) business which mainly consists of managed services for video collaboration and network and 2) the Oblong Industries business which consists of products and services for visual collaboration technologies. See Note 15 - Segment Reporting for further discussion.
Use of Estimates	Use of EstimatesPreparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from the estimates made. We continually evaluate estimates used in the preparation of our consolidated financial statements for reasonableness. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such periodic evaluation. The significant areas of estimation include determining the allowance for doubtful accounts, the estimated lives and recoverability of property and equipment, and intangible assets, the inputs used in the valuation of goodwill and intangible assets in connection with our impairment tests, the inputs used in the fair value of equity based awards as well as the values ascribed to assets acquired and liabilities assumed in the business combination.
Restricted cash	Restricted Cash As of December 31, 2020, our total cash balance was $5,277,000, consisting of available cash of $5,058,000, current restricted cash of $158,000, and $61,000 in long-term restricted cash. The long-term restricted cash is included in our other assets on our consolidated balance sheet. The restricted cash pertains to two letters of credit that serve as the security deposit for our leased office space in Munich, Germany and our leased office space in Los Altos, California (as discussed in Note 16 - Commitments and Contingencies ), and is secured by an equal amount of cash pledged as collateral, and such cash is held in a restricted bank account. As of February 28, 2021, the lease and the letter of credit ($158,000) for the Los Altos office space expired.
Allowance for Doubtful Accounts	Allowance for Doubtful AccountsWe perform ongoing credit evaluations of our customers. We record an allowance for doubtful accounts based on specifically identified amounts that are believed to be uncollectible. We also record additional allowances based on our aged receivables, which are determined based on historical experience and an assessment of the general financial conditions affecting our customer base. If our actual collections experience changes, revisions to our allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. We do not obtain collateral from our customers to secure accounts receivable.
Inventory	InventoryInventory consists of finished goods and was determined using average costs and was stated at the lower of cost or net realizable value. The Company periodically performs analyses to identify obsolete or slow-moving inventory,
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company considers its cash, accounts receivable, accounts payable and debt obligations to meet the definition of financial instruments. The carrying amount of cash, accounts receivable and accounts payable approximated their fair value due to the short maturities of these instruments. The carrying amounts of our debt obligations (see Note 10 - Debt ) approximate their fair values, which are based on borrowing rates that are available to the Company for loans with similar terms, collateral, and maturity. The Company measures fair value as required by Accounting Standards Codification (“ASC”) Topic 820 “Fair Value Measurements and Disclosures” (“ASC Topic 820”). ASC Topic 820 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. ASC Topic 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, there exists a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: • Level 1 - unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date. • Level 2 - inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. • Level 3 - unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date.
Revenue Recognition and Taxes Billed to Customers and Remitted to Taxing Authorities	Revenue Recognition The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606. The Company recognizes revenue using the five-step model as prescribed by Topic 606: • Identification of the contract, or contracts, with a customer; • Identification of the distinct performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when or as the Company satisfies a performance obligation. Oblong’s (formerly Glowpoint) managed videoconferencing services are offered to our customers on either a usage basis or on a subscription. Our network services are offered to our customers on a subscription basis. Revenue for these services is generally recognized on a monthly basis as services are performed. Revenue related to professional services is recognized at the time the services are performed. The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments are deferred on our consolidated balance sheet and amortized over the expected life of the customer contract. Deferred revenue as of December 31, 2020 totaled $27,000 as certain performance obligations were not satisfied as of this date. During the year ended December 31, 2020, the Company recorded $21,000 of revenue that was included in deferred revenue as of December 31, 2019. During the year ended December 31, 2019, the Company recorded $32,000 of revenue that was included in deferred revenue as of December 31, 2018. Oblong Industries’ visual collaboration products are composed of hardware and embedded software sold as a complete package, and generally include installation and maintenance services. Revenue for hardware and software is recognized upon shipment to the customer. Installation revenue is recognized upon completion of installation, which also triggers the beginning of recognition of revenue for maintenance services which range from one to three years. Revenue is recognized over time for maintenance services. Professional services are contracts with specific customers for software development, visual design, interaction design, engineering, and project support. These contracts vary in length, and revenue is recognized over time as services are rendered. Licensing agreements are for the Company’s core technology platform, g-speak, and are generally one year in length. Revenue for these services is recognized ratably over the service period. Upon adoption of Topic 606, Oblong Industries was not required to adjust its revenue recognition methodology, as recognition was deemed to be in-line with the five-step model. Deferred revenue as of December 31, 2020 totaled $1,696,000 as certain performance obligations were not satisfied as of this date. During the year ended December 31, 2020, the Company recorded $978,000 of revenue that was included in deferred revenue as of December 31, 2019. During the three months ended December 31, 2019, the Company recorded $352,000 of revenue that was included in deferred revenue as of the date of the merger. The Company disaggregates its revenue by geographic region. See Note 15 - Segment Reporting for more information. Taxes Billed to Customers and Remitted to Taxing Authorities
Impairment of Long-Lived Assets, Goodwill and Intangible Assets	Impairment of Long-Lived Assets, Goodwill and Intangible Assets The Company assesses the impairment of long-lived assets used in operations, primarily fixed assets and purchased intangible assets subject to amortization when events and circumstances indicate that the carrying value of the assets might not be recoverable. For purposes of evaluating the recoverability of fixed assets and amortizing intangible assets, the undiscounted cash flows estimated to be generated by those assets are compared to the carrying amounts of those assets. If and when the carrying values of the assets exceed the undiscounted cash flow, then the related assets will be written down to fair value. For the years ended December 31, 2020 and 2019, the Company recorded asset impairment charges on property and equipment of $144,000 and $63,000, which pertained primarily to assets no longer used in the business. During the year ended December 31, 2020, the Company disposed of fixed assets of $3,438,000, and the corresponding accumulated depreciation of $3,287,000, which resulted in a loss on disposal of $151,000. There were no impairments to purchased intangible assets for the years ended December 31, 2020 and 2019. For the year ended December 31, 2020, the Company recorded aggregate impairment charges of $465,000 on two right-of-use assets. See Note 16 - Commitments and Contingencies for further discussion. There were no impairments to right-of-use assets for the year ended December 31, 2019. Goodwill is not amortized but is subject to periodic testing for impairment in accordance with ASC Topic 350 “ Intangibles - Goodwill and Other - Testing Indefinite-Lived Intangible Assets for Impairment” (“ASC Topic 350”). During the years ended December 31, 2020 and 2019, the Company recorded impairment charges on goodwill of $541,000 and $2,254,000, respectively. See Note 7 - Goodwill and Note 8 - Intangible Assets ) for further discussion.
Concentration of Credit Risk	Concentration of Credit RiskFinancial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, and trade accounts receivable. We place our cash primarily in commercial checking accounts. Commercial bank balances may from time to time exceed federal insurance limits.
Property and Equipment	Property and Equipment Property and equipment are stated at cost and are depreciated over the estimated useful lives of the related assets, which range from three
Income Taxes	Income TaxesWe use the asset and liability method to determine our income tax expense or benefit. Deferred tax assets and liabilities are computed based on temporary differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that are expected to be in effect when the differences are expected to be recovered or settled. Any resulting net deferred tax assets are evaluated for recoverability and, accordingly, a valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax asset will not be realized.
Stock-based Compensation	Stock-based Compensation Stock-based awards have been accounted for as required by ASC Topic 718 “Compensation – Stock Compensation” (“ASC Topic 718”). Under ASC Topic 718 stock-based awards are valued at fair value on the date of grant, and that fair value is recognized over the requisite service period. The Company accounts for forfeitures when they occur.
Research and Development	Research and Development
Treasury Stock	Treasury StockPurchases and sales of treasury stock are accounted for using the cost method. Under this method, shares acquired are recorded at the acquisition price directly to the treasury stock account. Upon sale, the treasury stock account is reduced by the original acquisition price of the shares and any difference is recorded in additional paid in capital, on a first-in first-out basis. The Company does not recognize a gain or loss to income from the purchase and sale of treasury stock.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Credit Losses In June 2016 the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326),” which was subsequently amended in February 2020 by ASU 2020-02, “Financial Instruments - Credit Losses (Topic 326) and Leases (Topic 842).” The amendments introduce an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. The update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact the new guidance will have on its consolidated financial statements.
