Watch HDToday. Ten years ago, Survivor aired its twenty-eighth season, and changed the course of the CBS reality series as we know it. Survivor: Cagayan had eighteen dynamic characters stranded in the wilderness for the ultimate game of social strategy, divided into tribes that represented "brains," "brawn," and "beauty."
