The U.S. Department of Justice is suing to break up Live Nation, the parent company of Ticketmaster, over alleged antitrust violations. "The DOJ's complaint attempts to portray Live Nation and Ticketmaster as the cause of fan frustration with the live entertainment industry. Live Nation and Ticketmaster merged in 2010, creating a dominant entity in the live event industry. Through Ticketmaster, Live Nation controls roughly 80% or more of major concert venues' primary ticketing for concerts, the complaint said. Live Nation earlier this month reported its "biggest Q1 ever," citing first-quarter revenue that was up 21% from the prior-year period.
