The format used in the first season of "America's Got Talent" for live rounds differed greatly to what would later be used in both later seasons of the program and other international editions of the "Got Talent" franchise. Although the concept of airing the Results episode after a Performance episode on a different day would be retained in later seasons, the format of semi-final rounds and the final itself mainly had judges making votes about each performance pertaining to whether they approved or disapproved of an act, with no use of a buzzer to stop a performance at any times. The first season did incorporate the use of round for Wildcard acts for the contest, though a considerable number could be selected from any semi-final that they had been eliminated from, unlike in later seasons were the format was used. In the first season, the format's use was defined by the rule that the judges could each select two eliminated semi-finalists from any semi-final, while the public could choose one from each round.
