Silicon Valley hits Sun Valley — here's who's who at the 'summer camp for billionaires' in Idaho

Silicon Valley giants and media moguls alike are flocking to Idaho for Allen & Co.'s annual conference at Sun Valley Resort.

The " summer camp for billionaires" began Tuesday, and execs from Facebook, Disney, and PayPal are already in attendance. Historically, the conference has been a Petri dish for major mergers and acquisitions, including Jeff Bezos' purchase of the Washington Post and Comcast's acquisition of majority stake in NBCUniversal. One potential merger to watch unfold against the verdant backdrop of the resort this year could be CBS and Viacom.
