Liberty Media Chairman John Malone has been named interim chairman of the board of Live Nation Entertainment in the wake of IAC/Interactive Corp boss Barry Diller’s resignation. Mogul Barry Diller was rumored to have resigned because of a power struggle with Live Nation’s small but very mighty executive chairman and former talent manager, Irving Azoff. Live Nation, the live- events company that mainly focused on concert promotions, recently merged with Barry Diller’s Ticketmaster and became Live Nation Entertainment causing a major music industry coo and forever transforming the business. Diller remains on the board.
