American Idol
Each season premieres with the audition round, taking place in different cities. The audition episodes typically feature a mix of potential finalists, interesting characters and woefully inadequate contestants. Each successful contestant receives a golden ticket to proceed on to the next round in Hollywood. Based on their performances during the Hollywood round (Las Vegas round for seasons 10 onwards), 24 to 36 contestants are selected by the judges to participate in the semifinals. From the semifinal onwards the contestants perform their songs live, with the judges making their critiques after each performance. The contestants are voted for by the viewing public, and the outcome of the public votes is then revealed in the results show typically on the following night. The results shows feature group performances by the contestants as well as guest performers. The Top-three results show also features the homecoming events for the Top 3 finalists. The season reaches its climax in a two-hour results finale show, where the winner of the season is revealed.
