paragraph_text: David Archuleta's performance of John Lennon's "Imagine" was considered by many as one of the best of the season. Jennifer Lopez, who was brought in as a judge in season ten, called it a beautiful song-moment that she will never forget. Jason Castro's semi-final performance of "Hallelujah" also received considerable attention, and it propelled Jeff Buckley's version of the song to the top of the Billboard digital song chart. This was the first season in which contestants' recordings were released onto iTunes after their performances, and although sales information was not released so as not to prejudice the contest, leaked information indicated that contestants' songs frequently reached the top of iTunes sales charts.

In the first round the contestants emerged in groups but performed individually. For the next round, the contestants put themselves in small groups and perform a song together. In the final round, the contestants perform solo with a song of their choice a cappella or accompanied by a band‍—‌depending on the season. In seasons two and three, contestants were also asked to write original lyrics or melody in an additional round after the first round. In season seven, the group round was eliminated and contestants may, after a first solo performance and on judges approval, skip a second solo round and move directly to the final Hollywood round. In season twelve, the executive producers split up the females and males and chose the members to form the groups in the group round.

Its success in France led to two more albums and two novels.

It was extended with material from the third album in 2011.

paragraph_text: The most popular contestants are usually not revealed in the results show. Instead, typically the three contestants (two in later rounds) who received the lowest number of votes are called to the center of the stage. One of these three is usually sent to safety; however the two remaining are not necessarily the bottom two. The contestant with the fewest votes is then revealed and eliminated from the competition. A montage of the eliminated contestant's time on the show is played and they give their final performance. However, in season six, during the series' first ever Idol Gives Back episode, no contestant was eliminated, but on the following week, two were sent home. Moreover, starting in season eight, the judges may overturn viewers' decision with a "Judges' Save" if they unanimously agree to. "The save" can only be used once, and only up through the top five. In the eighth, ninth, tenth, and fourteenth seasons, a double elimination then took place in the week following the activation of the save, but in the eleventh and thirteenth seasons, a regular single elimination took place. The save was not activated in the twelfth season and consequently, a non-elimination took place in the week after its expiration with the votes then carrying over into the following week.

paragraph_text: In seasons ten and eleven, a further round was added in Las Vegas, where the contestants perform in groups based on a theme, followed by one final solo round to determine the semi-finalists. At the end of this stage of the competition, 24 to 36 contestants are selected to move on to the semi-final stage. In season twelve the Las Vegas round became a Sudden Death round, where the judges had to choose five guys and five girls each night (four nights) to make the top twenty. In season thirteen, a new round called "Hollywood or Home" was added, where if the judges were uncertain about some contestants, those contestants were required to perform soon after landing in Los Angeles, and those who failed to impress were sent back home before they reached Hollywood.

paragraph_text: During the live shows, a group of acts ranging from only a Top 20 (season two), to as many as 60, compete for viewers' and judges' votes. In the first season, the judges could not end an act's performance, but could either ``check ''or`` X'' the performance during their critique. Since season two (2007), judges have been able to end an act's performance early, and the ``check ''was removed. Generally, acts each perform first in a live round consisting of a series of quarterfinals. In seasons with YouTube auditions, the round of live judging of YouTube finalists takes place then, as part of these quarterfinals. Then there may be additional shows for`` Wild Card'' acts -- acts that one or more of the judges select to be given one more chance for audience vote despite previous elimination. From these shows, the existing group is narrowed through votes by the public and / or the judges (depending on the season). Acts then move on to a semifinal round, and even further rounds (such as a ``Top 8 ''or a`` Top 10'', depending on the season) through a series of weekly shows, which trim the number of acts down each time based on a public vote. In the majority of seasons, judges have had no vote from the semifinals. All these rounds culminate in a live final, which has consisted of anywhere from four to ten acts throughout the seasons. The act with the most votes is declared the winner, given $1 million, and, since season three (2008), a chance to headline a show on the Las Vegas Strip.

For the first five seasons, the recordings were released as a compilation album at the end of the season. All five of these albums reached the top ten in Billboard 200 which made then American Idol the most successful soundtrack franchise of any motion picture or television program. Starting late in season five, individual performances were released during the season as digital downloads, initially from the American Idol official website only. In season seven the live performances and studio recordings were made available during the season from iTunes when it joined as a sponsor.

paragraph_text: From the semi-finals onwards, the fate of the contestants is decided by public vote. During the contestant's performance as well as the recap at the end, a toll-free telephone number for each contestant is displayed on the screen. For a two-hour period after the episode ends (up to four hours for the finale) in each US time zone, viewers may call or send a text message to their preferred contestant's telephone number, and each call or text message is registered as a vote for that contestant. Viewers are allowed to vote as many times as they can within the two-hour voting window. However, the show reserves the right to discard votes by power dialers. One or more of the least popular contestants may be eliminated in successive weeks until a winner emerges. Over 110 million votes were cast in the first season, and by season ten the seasonal total had increased to nearly 750 million. Voting via text messaging was made available in the second season when AT&T Wireless joined as a sponsor of the show, and 7.5 million text messages were sent to American Idol that season.
