| Additional 402(v) Disclosure [Text Block] | TSR assumes that an investment of $100 was made in our Class A Common Stock and in each peer group company on December 31, 2019 and that all dividends were reinvested and is measured by dividing total dividends (assuming dividend reinvestment) plus share price change between the beginning and end of the measurement period by the share price at the beginning of the measurement period. The Peer Group is defined as the peer group as set by the Compensation Committee. For a list of companies included in the Peer Group, see Compensation Process within Compensation Discussion and Analysis above. Performance Measures. As discussed in Compensation Discussion and Analysis above, the primary objectives of our compensation program are to attract and retain the best available people while efficiently utilizing available resources, to enhance the executive officers’ overall performance, to align the long-term interests of our executive officers with those of our stockholders, to improve our overall business performance, and to reward individual performance. This is accomplished through a combination of base salary, long-term incentive compensation, and cash bonus designed to be competitive with comparable employers in the broadcast and media industry. The Compensation Committee considers both the Company’s overall performance and the individual’s performance when setting compensation levels. However, there are no set guidelines or policies outlining the weight of each, as the Compensation Committee assesses each factor at its discretion. For the year ended December 31, 2022, Adjusted EBITDA was the most important financial performance measure used to link executive compensation actually paid to company performance, and no other performance measures were used. | | |
