Fox has released a promo for the new to the U.S., Simon Cowell produced The X-Factor. The show will debut in 2011 when American Idol is on hiatus for the season. Cowell famously left America’s #1 show to produce and star on The X-Factor. The show is similar to Idol, but differs in the fact that each judge mentors a group of contestants, and then judges the other groups. The judges are highly involved in this series, and can make or break a contestant. Leona Lewis was the winner of a UK edition of the show.
