"It does feel like where we were 10 years ago with 'Idol,'" Cowell said of the U.S. "Factor" in an interview last week. "It's like new territory again. I've had to shed everything we did with the UK [version] and get into my head that this is a brand-new audience who actually knew nothing about this show.… It was really hard, first of all, because I've been doing the show for seven years. You sort of assume that everybody knows what you're doing and then you quickly realize, 'God, no one's got a clue.' You've got to explain the whole process and you've gotta get people interested from scratch."
