It's happy birthday The X Factor this week!
Yes, the singing talent show has been going for 15 years. The first series ran on ITV from 4 September 2004 to 11 December 2004.
So what does the future hold? And according to reports, former winners and celebrities will be taking part in not one, but two new series of The X Factor this year.
"The time feels right, and it will be a huge change," judge Simon Cowell said. "We haven't exactly confirmed the dates or the order of the shows, but essentially there are going to be two versions of X Factor running this year... I think it's going to be huge, it's the best I've felt about this show in years."
