The Company recognizes revenue when it satisfies a performance obligation under a contract with an advertiser. The transaction price is allocated to performance obligations based on executed contracts which represent relative standalone selling prices. Payment is generally due within 30 days although certain advertisers are required to pay in advance. Revenues are reported at the amount the Company expects to be entitled to receive under the contract. The Company has elected to use the practical expedient to expense sales commissions as incurred. Payments received from advertisers before the performance obligation is satisfied are recorded as deferred revenue in the balance sheet. Substantially all deferred revenue is recognized within twelve months of the payment date.

Each streamed commercial spot, station-owned asset and third party product is considered a performance obligation. Revenue is recognized when the commercial spots have streamed. Station-owned assets are generally scheduled over a period of time and revenue is recognized over time as the digital items are used for advertising content except for streamed commercial spots. Third-party products are generally scheduled over a period of time with an impression target each month. Revenue from the sale of third-party products is recognized over time as the digital items are used for advertising content and impression targets are met each month.

Other revenue includes revenue from concerts, promotional events, talent fees and other miscellaneous items. Revenue is generally recognized when the event is completed, as the promotional events are completed, or as the talent services are completed.
