Fox's long-running "American Idol" continued to show its age with the ratings from its season premiere Wednesday night.
The 13th season opener of "American Idol" drew an average 15.2 million viewers overall and earned a rating of 4.7 among key 18- to 49-year-olds. That's down 15% in total viewership compared with last year's premiere, and a drop of 22% in the young-adults demographic, continuing a downward trend since the show's premiere peak in 2007.
The singing competition fell to a season average of 13.2 million viewers last year, down 23% from 2012. Simon Cowell left the show at the end of the 2010 season.
