'American Idol' Changes Nights

The revamped "American Idol," will air on a different night for its upcoming 10th season.

The Fox TV network said its hit singing contest will move from its longtime Tuesday and Wednesday night slots to Wednesday and Thursday when it returns. The season debut is slated for Jan. 19.

The switch means more big change for "American Idol," which is bringing in new judges Steven Tyler and Jennifer Lopez after the departures of Simon Cowell, Ellen DeGeneres and Kara DioGuardi. Randy Jackson will be back on the panel.

Fox's decision to move the series, announced Friday, comes as "American Idol" must fight to keep its No. 1 spot. The show's ratings have been declining, with this year's finale between Lee Dewyze and runner-up Crystal Bowersox drawing about 24 million viewers, down 5 million from 2009.  Expect more little changes as we get close to the start of the season.
