Cityfile: New York's Most Notable and Influential

It's that time of year again, time for the Allen & Co's annual media industry confab in Sun Valley, Idaho. Occasionally described as a "summer camp for billionaires," the Herb Allen-hosted event is expected to atrract more than 250 media chiefs, tech moguls, financiers, Hollywood agents, and politicians, as well as the odd sports star or two. (LeBron James will be putting in an appearance this year.) Mostly, however, it will be populated by the sort of people who make it a point to show up every year, people like Bill Gates, Warren Buffett, Barry Diller, Sumner Redstone, and Rupert Murdoch, all of whom will undoubtedly be photographed over the coming days taking part in one of the many leisure activities arranged for attendees, like rafting, yoga, chess, bridge (a particular fave of Buffett and Gates), and biking (see Diller, left).
