The series is both a homage and satire of common conventions from reality television competition shows like Survivor. Each season revolves around a group of teens competing in an elimination-style competition, in that the contestants compete in challenges both as teams and individually for rewards and immunity from elimination. The teams merge roughly halfway through the competition into individuals. As the contestants develop relationships with each other, they are progressively eliminated from the game. When there are only two or three contestants remaining, they compete in a final challenge where the winner is awarded a cash prize: C$100,000 (US$73,129.00) in the first season, or C$1,000,000 (US$731,485.00) from the second season onward. The series currently consists of six seasons (Island, Action, World Tour, Revenge of the Island, the officially two-part All-Stars and Pahkitew Island (although separate seasons), and the two-part revival of Total Drama Island (the same as Pahkitew and All-Stars)).
