Pop Idol from 2001 in the UK
The creator of "American Idol," Simon Fuller, originally started with a show called "Pop Idol" in the UK, which also featured Simon Cowell. But the UK station didn't renew the contract for "Pop Idol" and instead replaced the show with a new program called "X-Factor" that Simon Cowell created. "Pop Idol" became "American Idol." "X-Factor" continues to run in the UK with Simon Cowell, but Simon Fuller just won a large chunk of its ownership because of the copyright violation.
