U.K. TV network ITV has agreed a new, three-year deal for "The X Factor" and "Britain's Got Talent" with Simon Cowell's Syco Entertainment and production company Fremantle Media.

As part of the renewal, the broadcaster has also acquired exclusive U.K. broadcast rights to the American version of "The X Factor" - due to air on Fox in the fall of 2011 - and America's Got Talent for ITV2.

The new agreement extends ITV's nine-year relationship with Simon Cowell until 2013. "Britain's Got Talent" will return to ITV1 in late-spring 2011, and next year's "The X Factor" returns in the fall.

It is still not clear what Cowell's on-screen presence will be in the U.K. edition of "The X Factor" from next year. He is reportedly in discussions with ITV over his participation as a judge in the U.K. shows, given his U.S. commitments. One option is for Cowell to sit out the audition rounds on "Britain's Got Talent."

"I am committed to making sure both shows get bigger and better every year," said Cowell in a statement. "I have a lot to thank ITV for; they have been key in making The X Factor and Britain's Got Talent the UK's biggest television shows."

Peter Fincham, ITV director of television, added: "The X Factor and Britain's Got Talent are the shows that have helped define the last decade of television in the U.K. and have become more than just a talking point: they are a national obsession, and I'm delighted that our viewers can continue to enjoy them on ITV over the next three years."

"The X Factor" and "Britain's Got Talent" are the U.K.'s most popular entertainment shows. Ratings for the Oct. 17 "X Factor" results show peaked at 15.2 million, the highest ever at this stage of the contest.

The agreement includes a new revenue share deal from downloads of live performances on iTunes, which are not chart eligible.
