paragraph_text: The general selection process of each season is begun by the production team with open auditions held in various cities across the United States. Dubbed ``Producers' Auditions '', they are held months before the main stage of auditions are held. Those that make it through the initial stage, become participants in the`` Judges' Auditions'', which are held in select cities across the country, and attended by the judges. Each participant is held offstage and awaits their turn to perform before the judges, whereupon they are given 90 seconds to demonstrate their act, with a live audience present for all performances. At the end of a performance, the judges give constructive criticism and feedback about what they saw, whereupon they each give a vote - a participant who receives a majority vote approving their performance, moves on to the next stage, otherwise they are eliminated from the programme at that stage. Each judge is given a buzzer, and may use it during a performance if they are unimpressed, hate what is being performed, or feel the act is a waste of their time; if a participant is buzzed by all judges, their performance is automatically over and they are eliminated without being given a vote. Many acts that move on may be cut by producers and may forfeit due to the limited slots available for the second performance. Filming for each season always takes place when the Judges' Auditions are taking place, with the show's presenter standing in the wings of each venue's stage to interview and give personal commentary on a participant's performance.
