Is Said to Investigate Ticketmaster’s Parent Company The inquiry predates the botched presale of Taylor Swift tickets this week and is said to focus on whether Live Nation has abused its power in the live music industry.Members of the antitrust division’s staff at the Justice Department have in recent months contacted music venues and players in the ticket market, asking about Live Nation’s practices and the wider dynamics of the industry, said the people, who spoke on the condition of anonymity because the investigation is sensitive.The new investigation is the latest scrutiny of Live Nation Entertainment, which is the product of a merger between Live Nation and Ticketmaster that the Justice Department approved in 2010.It extended the terms of the settlement by five years, to 2025, and adjusted some of the agreement’s language to clarify what the company was allowed to do when negotiating ticketing deals with venues.Members of the Justice Department staff have asked whether Live Nation is complying with the agreement as part of their new inquiry, said one of the people with knowledge of the matter."
