American Idol (season 15)

For the first time, performances by the top 24 were judged solely by the show's judges and producers, who determined which contestants were eliminated. From each group of twelve, seven were advanced and five were eliminated, resulting in a top 14 for the third week of the semifinals.

The voting limit for this season was set at ten votes per contestant per voting method, half of what it had been the previous season.[4]
