Call it summer camp for billionaires.
Every July, some of the globe's biggest media tycoons descend on the Wood River Valley for the annual Allen & Co. media conference, getting underway this week. The attendees are supposed to remain hush-hush ... but the armada of private jets at Friedman Memorial Airport in Hailey becomes rather obvious.
Bloomberg Business is reporting Apple CEO Steve Jobs is in Sun Valley ... as is News Corp. CEO Rupert Murdoch, Berkshire Hathaway CEO Warren Buffett, Microsoft Chairman Bill Gates, Disney CEO Bob Iger, Facebook CEO Mark Zuckerberg and Google CEO Eric Schmidt. Ironically, the event is officially closed to the press, but past events have included off-the-record business presentations, along with yoga, golf, trap and skeet tournaments, tennis, barbecues and cocktails at the Sun Valley Resort. It's the 28th annual event.
