Sinclair Broadcast Group is a publicly traded media company headquartered in Hunt Valley, Maryland, and one of the largest and most diversified television broadcasting companies in the United States. The company owns, operates, or provides services to nearly 200 television stations across the country, reaching a significant portion of U.S. television households. Sinclair's portfolio spans local news, sports, and entertainment programming, and the company has made substantial investments in digital and streaming platforms to complement its traditional broadcast footprint. In the AdTech and advertising space, Sinclair has developed and invested in advanced advertising capabilities, including programmatic advertising, targeted local TV advertising, and data-driven audience solutions. The company operates Compulse, a digital marketing solutions division that provides managed digital advertising services to local businesses and advertisers.
