Ticketmaster
Ticketmaster Entertainment, Inc. is an American company specializing in ticketing services for live events, including concerts, sports, and theater.[1] Founded in 1976 in Phoenix, Arizona, by university staffers Albert Leffler, Peter Gadwa, and businessman Gordon Gunn, it initially focused on developing and selling ticketing hardware and software systems.[2] Since merging with Live Nation in 2010 to form Live Nation Entertainment, Inc., Ticketmaster has operated as a wholly owned subsidiary, integrating promotion, venue management, and primary ticketing under one entity.[3] It commands a dominant position in the U.S. market, handling over 70% of primary ticketing for live concerts and events through exclusive venue contracts and artist agreements.[4] This market power has drawn antitrust challenges, including a 2024 U.S. Department of Justice lawsuit alleging monopolization across live concert markets and a 2025 Federal Trade Commission suit accusing deceptive practices in ticket resale and fee disclosures.[5][6]
