In an appointment seasoned with a dash of corporate irony, Liberty Media chairman John Malone has been named interim chairman of the board at Live Nation Entertainment in the wake of Barry Diller’s resignation.Diller officially tendered his resignation at the concert promotion, ticketing and management company’s Oct. 14 board meeting, the company said. In 2008, Diller and Liberty filed a barrage of lawsuits against each other over voting rights pertaining to Diller’s desire to split his company, IAC, into five separate companies. It had been rumored that Diller’s conflict with some LNE board members, including Malone, had spurred his resignation. However, both men denied that their sometimes stormy relationship had anything to do with the move (Daily Variety, Oct. 4). Diller has said his tenure on the LNE board was always intended to be temporary.
