The second season of American Idol premiered on January 21, 2003, and continued until May 21, 2003. The title of show was shortened from American Idol: The Search for a Superstar to just American Idol. Ryan Seacrest returned as the host after Brian Dunkleman quit after the previous season, and Seacrest became the lone host beginning with this season.

The second season was won by Ruben Studdard, who defeated Clay Aiken by 134,000 votes out of the 24 million votes recorded.

Studdard released his coronation song "Flying Without Wings" after the show, which reached number two on the U.S. Billboard Hot 100. Aiken also released a single with "This Is the Night." He was the first non-winning contestant to have a Billboard Hot 100 number one. It was also the biggest U.S. single of 2003, selling over one million copies and reaching six times platinum status in Canada as well as number one in New Zealand.

In addition to Studdard and Aiken, Kimberley Locke, Joshua Gracin, Kimberly Caldwell, and Carmen Rasmusen all signed with various record labels.

The number of auditions increased significantly after the success of the first season, and arenas and stadiums began to be used to hold the first auditions from this season onward. Around 70,000 attended auditions this season and 234 were selected to proceed on to the Hollywood round. Radio DJ Angie Martinez was originally signed up as a fourth judge, but quit after a few days, stating that "it became too uncomfortable for me to tell someone else to give up on their dream."

Amber Riley was rejected by producers and did not get to audition for the judges, but later went on to co-star on the television series Glee as Mercedes Jones.

Hollywood week The contestants performed in a series of rounds and the number of contestants trimmed was in each round. In the first round, the 234 contestants performed a song, after which 114 were eliminated. In the second round, the remaining 120 contestants were asked to compose a melody for one of five sets of lyrics, and 40 more were cut. In the third round, the contestants were separated by gender and performed in small groups. The remaining 48 boys chose from The Carpenters' "Superstar," Seal's "Kiss from a Rose," and Barry Manilow's "Tryin' to Get the Feeling Again," while the remaining 32 girls chose from Melissa Manchester's "Don't Cry Out Loud," Freda Payne's "Band of Gold," and Dionne Warwick's "You'll Never Get to Heaven (If You Break My Heart)."

In the last round, each of the remaining 48 contestants performed solo. After their performances, the contestants were then divided into three groups of sixteen and placed in separate rooms. One group was eliminated, and 32 contestants proceeded on to the semifinal rounds.

Semifinals The format changed slightly in the second season; instead of three groups of ten, the semifinalists were grouped into four groups of eight. The singers performed solo on a new and improved stage with piano accompaniment by Michael Orland, and the performances were pre-taped. There was no live audience, although family members of contestants were present in the Red Room where the contestants were placed.

The results of the public vote were announced live the next day. From each group, two were selected to proceed on to the top 12. Nine of those who failed at any of previous stages, including the Hollywood rounds and the initial regional auditions, were given one more chance to perform again in the Wild Card show. Each of the three judges put one contestant from the Wild Card group through to the top 12, with the final one selected by the public vote.
