Supporting herself with numerous odd jobs, Clarkson made a few television appearances and eventually landed a job working as a female vocalist with songwriter Gerry Goffin. Unfortunately, a bout of bad luck discouraged her and she returned to Texas shortly thereafter. In 2002, a friend told her about a new talent search show on Fox called American Idol, and Clarkson became one of 10,000 contestants.
After grueling rounds of televised eliminations, and critical evaluations by judges Paula Abdul, Simon Cowell and Randy Jackson, Clarkson prevailed against Justin Guarini to become the first winner of the hit contest on September 4, 2002. Her official prize was a million-dollar RCA record contract; the unofficial prize a considerable amount of fame and notoriety.
The following month, her first single, "A Moment Like This," went from No. 52 to No. 1 on the Billboard charts. In 2003, she made her feature film debut in the forgettable From Justin to Kelly. Fortunately, her first album fared much better than her movie. Thankful was a hit based in part because of the smash single, "Miss Independent." And Clarkson went on to establish herself as a leading rock performer with her second album, Breakaway (2004). The album spawned several big hits, including Since U Been Gone, Breakaway, Behind These Hazel Eyes, and Walk Away. It also earned Clarkson two Grammy Awards in 2005: one for Best Female Pop Vocal Performance for Since U Been Gone and another for Best Pop Vocal Albuman award she shared with producer Clive Davis and engineer/mixer Serban Ghenea.
After selling millions of records, Clarkson was under a lot of pressure to keep the hits coming. But she wanted to try something different. Clarkson did not use professional songwriters as she had in the past and filled the record with songs that she co-wrote. The result led to a clash with Clive Davis, over the album, My December (2007), after he suggested it needed to reworked. Davis expressed concern that there were no singles on the album and others indicated that its overall tone was too negative. But Clarkson refused to change what she considered to be a very personal recording.
