Lamar Advertising Company is one of the largest outdoor advertising companies in the United States, operating integrated advertising services across billboards, logo signs, and transit displays. The company generates revenue by renting advertising display space to customers under fixed-term contracts, offering displays ranging from large bulletins and digital LED billboards on major highways to smaller posters on city streets, logo signs near highway exits, and transit advertising on buses, shelters, and airport terminals across dozens of states and Canada. Its customer base is geographically diversified across multiple advertiser categories—including service, healthcare, restaurants, and retail—with revenue derived primarily from local advertising, and the company complements display rental with full-service creative production and installation services.
