The X Factor is a television music competition franchise created by Simon Cowell. It originated in the United Kingdom, where it was devised as a replacement for Pop Idol (2001–2003). It is held in various countries. The programmes are produced by executive producer Simon Cowell and his company SYCOtv. The "X Factor" of the title refers to the undefinable "something" that makes for star quality. The prize is usually a recording contract, in addition to the publicity that appearance in the later stages of the show itself generates, not only for the winner but also for other highly ranked contestants.
The similarities between The X Factor and Idols prompted Idol creator Simon Fuller, along with 19 Entertainment, to file a lawsuit against Cowell, SYCOtv, and FremantleMedia in 2004. An out-of-court settlement was reached in 2005 allowing Fuller to gain a 10% share in The X Factor format, and preventing an American version until 2010. Fuller later filed another lawsuit in 2011, claiming that he had also been promised that he would be credited as an executive producer of The X Factor USA, but that Syco, FremantleMedia, and Fox Broadcasting Company had failed to fulfill that promise; that lawsuit is pending.
