Subsequent Events [Abstract]
Subsequent Events	17. SUBSEQUENT EVENTS In March 2022, a bonus award of $1.3 million was approved and granted to certain employees based on their service and results in 2021. These awards are to be paid partially in cash and partially in restricted stock awards, which vest immediately upon grant in March 2022. For the year ended December 31, 2021, we recorded $0.5 million of expense related to the cash portion of the awards, of which $0.2 million and $0.3 million are included in Operating expenses excluding depreciation and amortization expense and Corporate expenses, respectively. $0.8 million was recorded as stock-based compensation expense in 2022. In March 2022, the Company extended the time we are able to make additional draws on the May 2021 SG Broadcasting Promissory Note. See Note 6 for further discussion.
