Barry Diller is stepping down as CEO of IAC, to be succeeded by Greg Blatt, the current CEO of IAC’s Match.com. Diller will remain as IAC’s chairman and its largest shareholder, with a voting share of up to 41 percent. “It’s been clear to me for some time that this company needs a full time aggressive and aspirational executive in the CEO role,” Diller said in a statement Thursday. IAC is also buying out Liberty Media’s 60 percent voting stake for $220 million in exchange for two IAC properties, Evite and Gifts.com. The Daily Beast, which just agreed to merge with Newsweek, is an IAC property.
