Results shows for American Idol that air on Thursdays never do so well in the ratings as those that air on Wednesdays, and this week's Thursday episode was no exception. It also had the bad fortune of airing opposite NBC's Olympics coverage -- on the night that NBC once owned, calling Thursdays "Must See TV Night." So while the competition on ice and snow drew 22.49 million viewers, Idol attracted 17.83 million -- a huge number for any other show but the equivalent of a crash on the ice for Idol . Meanwile, despite the competition from both the Olympics and Idol , CBS's Survivor Heroes vs. Villains heroically came in third with a solid 11.51 million viewers.
