For the six months ended June 30, 2023, consolidated net operating revenue was $54,479,000 compared with $54,788,000 for the six months ended June 30, 2022, a decrease of $309,000 or 0.6%. We had decreases in gross local revenue of $956,000, and gross political revenue of $606,000, and an increase in agency commissions of $108,000 partially offset by increases in gross interactive revenue of $535,000, gross national revenue of $447,000 and gross non-spot revenue of $435,000, from 2022. The decrease in gross local revenues was attributable to decreases at our Charleston, South Carolina; Columbus, Ohio; Ithaca, New York; Milwaukee, Wisconsin; and Springfield, Illinois markets partially offset by increases at our Asheville, North Carolina; Bellingham, Washington and Charlottesville, Virginia markets. The gross political revenue decreased due to a decrease in the number of national, state and local elections. The increase in agency commissions is due to increases in both our national and local agency revenue. The increase in gross interactive revenue is primarily due to an increase in our streaming revenue. The most significant increases in gross national revenue occurred in our Charlottesville, Virginia; Des Moines, Iowa; Norfolk, Virginia and Ocala, Florida markets. The most significant increases in gross non-spot revenue occurred in our Charleston, South Carolina; Milwaukee, Wisconsin; Ocala, Florida and Yankton, South Dakota markets.
Station operating expense was $44,110,000 for the six months ended June 30, 2023, compared with $42,354,000 for the six months ended June 30, 2022, an increase of $1,756,000 or 4.1%. The increase in operating expense was primarily a result of increases in compensation-related expense, utility expenses, sales commission expenses, building maintenance and repairs, programming rights expense, sales rating survey expenses, sales training expenses, music licensing fees and promotional expenses, of $822,000, $166,000, $161,000, $146,000, $113,000, $87,000, $48,000, $47,000 and $46,000, respectively, for the comparable period of 2022.
We had operating income for the six months ended June 30, 2023 of $5,201,000 compared to $7,091,000 for the six months ended June 30, 2022, a decrease of $1,890,000. The decrease was a result of the decrease in net operating revenue and the increase in station operating expense, as noted above, an increase in other operating (income) expense, net of $40,000 partially offset by a decrease in corporate general and administrative expenses of $215,000. In 2023, we recorded a loss on the sale of fixed assets of $80,000 compared to a loss on the sale of fixed assets of $40,000 in 2022. The decrease in corporate general and administrative expenses was primarily comprised of a decrease of $502,000 in compensation-related expense partially offset by an increase of $131,000 in directors’ fees and $195,000 in other consulting fees.
We generated net income of $4,270,000 ($0.70 per share on a fully diluted basis) during the six months ended June 30, 2023, compared to $5,027,000 ($0.83 per share on a fully diluted basis) for the six months ended June 30, 2022 ended, a decrease of $757,000. The decrease in net income is primarily due to the decrease in operating income, described above, an increase in interest expense of $22,000 partially offset by an increase in interest income of $583,000, an increase in other income of $117,000 and an increase in income tax expense of $455,000. The increase in interest expense is due to an increase in interest rates and amortization of bank fees. The increase in interest income is related to higher rates of return on money market accounts reflected as cash equivalents and from our short-term investment accounts which began in May 2022. The increase in other income is due to reimbursements from the FCC related to their spectrum auction of $115,000 described in footnote 13 (Other Income) versus the minimal other income earned in 2022. The decrease in our income tax expense is due to the decrease in income before income tax.
