Document 12: American Idol: In what was to become a tradition, Clarkson performed the coronation song during the finale, and released the song immediately after the season ended. The single, "A Moment Like This", went on to break a 38-year-old record held by The Beatles for the biggest leap to number one on the Billboard Hot 100. Guarini did not release any song immediately after the show and remains the only runner-up not to do so. Both Clarkson and Guarini made a musical film, From Justin to Kelly, which was released in 2003 but was widely panned. Clarkson has since become the most successful Idol contestant internationally, with worldwide album sales of more than 23 million.
Document 13: American Idol: The two finalists were Kris Allen and Adam Lambert, both of whom had previously landed in the bottom three at the top five. Allen won the contest in the most controversial voting result since season two. It was claimed, later retracted, that 38 million of the 100 million votes cast on the night came from Allen's home state of Arkansas alone, and that AT&T employees unfairly influenced the votes by giving lessons on power-texting at viewing parties in Arkansas.
Document 14: Kelly Clarkson: Kelly Brianne Clarkson (born April 24, 1982) is an American singer and songwriter. She rose to fame in 2002 after winning the inaugural season of the television series American Idol, which earned her a record deal with RCA Records. Clarkson's debut single, ``A Moment Like This '', topped the US Billboard Hot 100 chart and became the country's best - selling single of 2002. It was followed by the release of her debut album, Thankful (2003), which debuted atop the US Billboard 200. Trying to reinvent her image, Clarkson decided to part ways with Idol management and her second album, Breakaway (2004), featured a pop rock sound. It sold over 12 million copies worldwide and earned Clarkson two Grammy Awards.
Document 15: American Idol: Both finalists found success after the show, but Aiken out-performed Studdard's coronation song "Flying Without Wings" with his single release from the show "This Is the Night", as well as in their subsequent album releases.
