It is expected that Simon Cowell’s departure from American Idol will be announced later today after months of speculation, at the same time as The X Factor (US) is announced.
Sources confirm to Hollywood Reporter exclusively that Cowell will quit the top-rated show on television at the end of this season as part of his plan to focus on launching a new series, “The X-Factor.” Fox has picked up “Factor” for the fall of 2011, when “Idol” is on hiatus.
