A jury has found that concert giant Live Nation and its Ticketmaster subsidiary engaged in an anticompetitive monopoly. They jury in New York decided Wednesday on claims from dozens of U.S. states that the entertainment ticketing behemoth was a monopoly that cost concertgoers and sports fans. Live Nation Entertainment owns, operates, controls booking for or has an equity interest in hundreds of venues. Its subsidiary Ticketmaster is widely considered to be the world’s largest ticket-seller for live events. The civil case, initially led by the U.S. federal government, accused Live Nation of using its reach to smother competition.
