Viacom’s Dauman to Join Media Bigs in Sun Valley

Deadline: Viacom CEO Philippe Dauman and rival Shari Redstone may be spending some time together next month at Allen & Co.’s Sun Valley retreat. Both are invited to the yearly gathering – which could see the two uncomfortably hanging out in Idaho with the likes of Bob Iger, Harvey Weinstein, Jeffrey Katzenberg, Les Moonves and other CEOs.
