Cowell would leave American Idol after season 9 in order to bring The X Factor to the United States in September 2011. Cowell told the Television Critics Association that he was leaving American Idol so that he could judge and act as executive producer of the U.S. version of The X Factor. Additionally, Cowell signed a long-term contract with Sony Music, who already supported Syco Music artists in the UK, under which he was involved with the production of the U.S. version of the show and also worked with the artists who won recording contracts. In November 2010, Fox began airing short commercials for the program, which displayed the text "Coming to America Fall 2011". The New York Times described the commercials as efforts by the network to set up the launch of The X Factor as a television "event." In February 2011, during Super Bowl XLV, Fox unveiled the official logo for the show in a promo starring Cowell. A second promo was shown during the course of that evening, featuring Katy Perry, Justin Bieber, The Black Eyed Peas, Usher, Lady Gaga, the Pussycat Dolls, and Madonna. This promo gave rise to speculation about who would join Cowell on the X Factor judging panel. Format Categories The show is primarily concerned with identifying singing talent, though appearance, personality, stage presence and dance routines are also an important element of many performances. Each judge is assigned one of four categories, to use their experience to help the artists. For season one, these categories were: "Boys" (aged 12–29 males), "Girls" (aged 12–29 females), "Over 30s" (solo acts aged 30 and over), and "Groups" (including duos). Season two's categories and age group boundaries were changed, with the "Boys" and "Girls" categories becoming "Teens" (solo acts aged 12–17) and "Young Adults" (solo acts aged 18–24), and the "Over 30s" became "Over 25s" (solo acts aged 25 and over). For both seasons, some groups were formed from soloists and other groups rejected after the audition process. Through the live shows, the judges act as mentors to their category, helping to decide song choices, styling, and staging, while judging contestants from other categories. Season three’s categories and age group boundaries were changed, with the "Teens" and "Youth Adults" categories becoming back as "Boys" (aged 12–24 males) and "Girls" (aged 12–24 females) and the "Over 25s" (solo acts aged 25 and over).
