The X Factor, also known as The X Factor USA, is an American reality television music competition show created by Simon Cowell and produced by FremantleMedia North America and SYCOtv, a partnership between Cowell and Sony Music Entertainment, which aired on Fox. Based on the original British show, and an addition to The X Factor franchise, the series found new singing talent (solo artists and groups ages 12 and over), drawn from public auditions, and they competed against each other for votes. The winners were determined by the show's viewers via telephone, the Internet, and SMS text voting, and were awarded a recording contract with Cowell's record label Syco Music, worth $5 million in seasons one and two, and $1 million in season three. America voted for the following winners: Melanie Amaro, Tate Stevens, and Alex & Sierra, respectively.

The show began airing on September 21, 2011, through negative reviews, and aired annually from September through December. The series employs a panel of judges who critique the contestants' performances. Each contestant is assigned to one of four categories. The group acts are one category and the others are based on age or gender. For example, in season 1 the categories were girls, boys, groups, and over 30s. Each judge was assigned to one of the categories, and acted as a mentor to the contestants in their category, helping with song choices, styling, and staging, while also judging contestants from the other categories after each of the live performances. They competed with each other to try to get one of the contestants in their category to win the competition, thus making them the winning judge.

The most successful act to emerge from the series is Fifth Harmony, with all members launching solo careers.

The original judging panel consisted of Cowell, Paula Abdul, Cheryl Cole, and L.A. Reid, with Nicole Scherzinger and Steve Jones as co-hosts. Scherzinger would later replace Cole on the judging panel after two audition sites. Demi Lovato and Britney Spears joined the panel in the second season as replacements for Abdul and Scherzinger, while Khloé Kardashian and Mario Lopez replaced Jones as co-hosts. Reid and Spears did not return for the third season and were replaced by Kelly Rowland and Paulina Rubio, while Lopez became sole host after Kardashian was not asked to come back.

Announcement and launch On January 11, 2010, News Corporation (via Fox News in the U.S. and The Times in the UK) reported that 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 American version of The X Factor. Retrieved January 11, 2010. 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 American 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, 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).

Stages for seasons 1 and 2 There are five stages to the competition: Stage 1: Producers' auditions (these auditions decide who will sing in front of the judges) Stage 2: Judges' auditions Stage 3: Boot camp Stage 4: Judges' houses Stage 5: Live shows (finals)

Stages for season 3 There are four stages to the competition: Stage 1: Producers' audition (these auditions decide who will sing in front of the judges) Stage 2: Judges' auditions Stage 3: Four-chair challenge Stage 4: Live shows (finals)

Auditions The show is open to solo artists and vocal groups aged 12 and above, with no upper age limit. Applicants are given an opportunity to apply by uploading a video audition to the Internet. The show's producers also send a "mobile audition van" to various locations throughout the U.S. to audition singers who are unable to attend the arena auditions. A round of first auditions is held in front of producers months before the show is aired, some by application and appointment, and others in "open" auditions that anyone can attend. These auditions, held at various venues around the U.S., attract very large crowds. The producers' auditions are not televised, but shots of crowds waving and "judges' cars" arriving are filmed and later spliced in with the televised auditions shot later in the year. After waiting at the venue for hours (during which crews film more shots of crowds screaming and waving), each candidate is given a brief audition by someone from the production team. If they pass that audition (either because of their talent or because the producers think they will make entertaining television), they are given a "golden ticket" that allows them to audition for a more senior member of the production team. Only candidates who successfully pass this second audition (and then a third along similar lines) are invited to perform in front of the judges. (The televised version misleadingly gives the impression that everyone in the huge crowds shown is waiting for a chance to perform for the judges.)

A selection of the auditions in front of the judges – usually the best, the worst and the most bizarre – are broadcast during the first few weeks of the show. The judges' auditions are held in front of a live audience, and the acts sing over a backing track. If a majority of the judges (in this case, at least three judges) have to say "yes" then the act goes through to the next stage, otherwise, they are sent home.

Boot camp and judges' houses In the first two seasons, The contestants selected at the auditions were further refined through a series of performances at "boot camp", and then at the "judges' houses", until a small number eventually progressed to the live finals (seventeen in season 1, and sixteen in season 2).

At boot camp, the judges collaboratively chose a small number of acts (32 in season 1 with eight in each category; 24 in season 2 with six in each category) for the next round, "judges' houses". The producers then assigned each of the judges a category to mentor, and the judges split up for the "judges' houses" round, in which each of them hosted the contestants in their assigned category at a luxurious residence, often scattered around the globe. The houses the contestants visited did not in every case actually belong to the judges, some were rented for the occasion.

The contestants did not know who their mentor would be until they arrived at that judge's house.

During this round, each judge held another round of auditions on location, and then further reduced the number of acts with the help of a celebrity guest.

In season three, these stages of the competition are being replaced by a new stage called "The Six-Chair Challenge", first introduced in the Dutch version of the series.

Live shows

The selected contestants (either 16 or 17 acts) move into shared accommodation at the Hollywood Hills to take part in the show. The mansion is also notably used for housing the finalists from American Idol.

The finals consist of a series of two live shows, the first featuring the contestants' performances and the second revealing the results of the public voting, culminating in one or more acts being eliminated. Celebrity guest performers also feature regularly. These live shows are filmed at CBS Television City in Los Angeles, California. The performance shows were broadcast on Wednesday nights and the results show on Thursday nights. In season one, seventeen acts were put through to the live shows, and sixteen acts were put through in season two.

In addition to the live broadcast on Fox, Sony and SYCOtv created a completely integrated second-screen experience and a Pepsi sponsored live digital pre-show known as The X Factor Digital Experience. In addition to watching the program live on television, the audience was now able to participate on multiple platforms in real-time.

Performances The show is primarily concerned with identifying a potential pop star or star group, and singing talent, appearance, personality, stage presence and dance routines are all important elements of the contestants' performances. In the initial live shows, each act performs once in the first show in front of a studio audience and the judges, usually singing over a pre-recorded backing track. Dancers are also commonly featured. Acts occasionally accompany themselves on guitar or piano. Each live show has had a different theme; each contestant's song is chosen according to the theme. After each act has performed, the judges comment on their performance. Heated disagreements, usually involving judges defending their contestants against criticism, are a regular feature of the show. Once all the acts have appeared, the phone lines open and the viewing public vote on which act they want to keep. Once the number of contestants has been reduced to five (season 1), or six (season 2), each act would perform twice in the performances show. This continues until only three acts remain. These acts go on to appear in the grand final which decides the overall winner by public vote.

Results Before the results are announced, the results show occasionally begins with a group performance from the remaining contestants. However, the song is pre-recorded and the contestants mime, due to problems with the number of microphones. The two acts polling the fewest votes are revealed. Both these acts perform again in a "final showdown", and the judges vote on which of the two to send home. They were able to pick new songs to perform in the "final showdown". "Double elimination" took place in some of the results shows, where the bottom three acts were revealed and the act with the fewest votes was automatically eliminated, and the two with the next fewest votes performed in the "final showdown" as normal. In season two, at the end of each result show, the rankings of the acts based on the public votes were announced.
