The second season of "America's Got Talent", an American talent show competition, was broadcast in the United States during 2007, from June 5 to August 21 on NBC; the network originally intended for it to run during its winter schedule that year, but opted against it following concerns over it clashing with other major broadcasts at that time. In the wake of the success of the first season, additional episodes were commissioned by NBC, with production staff making changes to the program's format for the new season. These included the addition of a "bootcamp" stage of auditions, and amendments to the involvement of the judges and the use of their buzzers to match that with other editions across the "Got Talent" franchise, in particular the British edition.
