Survivor is a British competition television series based on the international reality franchise of the same name. The series aired for two series on ITV network in 2001 and 2002, before being revived in 2023 by BBC. Following the premise of other versions of the format, the show features a group of contestants become castaways as they are marooned in an isolated location, where they must provide food, water, fire, and shelter for themselves. The contestants compete in challenges for rewards and immunity from elimination. The contestants are progressively eliminated from the game as they are voted off the island by their fellow castaways. The final castaway remaining is awarded the title of "Ultimate Survivor" and a monetary prize. While it was considered a failure in the ratings by ITV, the programme was watched by more viewers than other reality series at the time, including Big Brother. ITV cancelled Survivor after two series after it had failed to garner a loyal viewership. The network admitted fault for not supporting the series enough in its launch phase, highlighting the key issue with their approach to be the scheduling of the series. Since 2017, reports that the series would be revived had circulated in the media, with BBC One confirming this in 2022. Format The show follows the same general format as the other editions of Survivor. To begin, the players are split into two or three tribes, are taken to a remote isolated location and are forced to live off the land with meagre supplies for a period of several weeks. Frequent physical and mental challenges are used to pit the tribes against each other for rewards, such as food or luxuries, or for immunity, forcing the other tribe to attend Tribal Council, where they must vote one of their tribemates out of the game by secret ballot. About halfway through the game, the tribes are merged into a single tribe, and challenges are on an individual basis; winning immunity prevents that player from being voted out. Most players that are voted out during this stage become members of the Tribal Council Jury. When only two or three players remain, the Final Tribal Council is held. The finalists plead their case to the Jury as to why they should win the game. The jurors then have the opportunity to interrogate the finalists before casting their vote for which finalist should be
