The "American Idol" live shows are filmed at the same time they are shown on live TV beginning in January of each year, as of 2015. During the 2015 season, the live shows began a week earlier than usual due to the addition of Rush Week to the competition.
The 2015 "American Idol" Rush Week featured 31 performers performing in live shows with the show's judges cutting the contestant count down to 20. Live voting to determine who is eliminated each week is typically a major element of the live shows. In 2015, for the first time the audience has the option to start voting from the time the show starts rather than having to wait for each episode to end.
