Title: America's Got Talent (season 1)
Content:  The first season of American talent show competition series America's Got Talent was broadcast on NBC from June 21 to August 17, 2006. The season went into production a year earlier than planned by Got Talent creator Simon Cowell, who had intended for Britain's Got Talent to debut first in 2006 until its production was suspended, following internal conflicts within its British television network. For its first season, production staff appointed David Hasselhoff, Brandy Norwood, and Piers Morgan to be the program's first judges, and its first host to be Regis Philbin. Unusually, this season involved an early format for live round judging and Wildcard acts that would be later changed after the season's conclusion. The first season was won by singer Bianca Ryan, with clogging dance group All That and singer & musician duo The Millers finishing as runner-ups within the Top 3 finalists; the season's actual results for second and third place were not declared. The success of this season, per its ratings, helped to foster development of other international editions of the Got Talent franchise, along with restarting production on the British edition.

On March 9, 2021, it was announced that the season would premiere on June 1.

Content:  The first season for America's Got Talent was promoted in May 2006, and was eventually aired later that year between June 21 to August 17. While later episodes would pre-record auditions at earlier dates, this season saw them conducted across June, atvenues within the cities of New York, Chicago, and Los Angeles, with live-round episodes held within the latter city. Initial advertisements for participants for America's Got Talent implied that the winning act would headline a show in Las Vegas, but this was later dropped in favour of a cash prize of $1 million due to concerns surrounding the possibility of awarding such a prize to a minor.

Other changes included the "bootcamp" round being filmed in New York for this season, and the introduction of a new online vote for viewers, named after the program's sponsor during that season, to decide which three act placed in the mid-range of the public vote - 5th, 6th and 7th in the semi-finals; and 4th, 5th and 6th in the "Top 12" round - would be advanced, with the remaining two voted upon by the judges.

The second season saw the introduction of a new round in the audition process, which was referred to as the "bootcamp stage" - a period of callback episodes filmed in Las Vegas, aimed at streamlining successful participants from the first round of auditions towards a set number for the live rounds. Alongside this, participants in the live rounds moved on via the public vote only, while the episode for results was aired a week after each live episode's performance and within a smaller timeslot for its broadcast. This season was won by singing impressionist and ventriloquist Terry Fator, with singer and guitarist Cas Haley coming in second, and singer Butterscotch placing third.
