Total Drama Island (sometimes shortened to TDI) is a Canadian animated television series which lampoons the conventions commonly found in reality shows. The show and its sequel seasons are collectively referred to as the Total Drama series. It premiered on the Canadian cable television specialty channel Teletoon on July 8, 2007. The show was created by the creators of 6teen, another Teletoon program. It was the third Cartoon Network show outside of Adult Swim and Toonami to have the U.S. rating of "TV-PG-D", and a parental-guidance warning after every commercial break and at the beginning of the show (the first two being Sunday Pants and IGPX; its rating in Canada for most episodes is "G", or else "PG"). On the Cartoon Network airing in the United States, some content has been removed from the episodes by censors in order to keep the rating open to a younger audience; for example, putting in words instead of long bleeps, for the episodes "That's Off the Chain" and "Trial by Tri-Armed Triathlon". As of now, reruns are not seen on Cartoon Network. The fourth season, Total Drama: Revenge of the Island is also shown in the same location except with a new cast.
