siobhan idol top 12 320 TV ratings: 'American Idol' stones Tuesday foes but down from last yearFast National ratings for Tuesday, March 16, 2010

“American Idol’s” top 12 covered the Rolling Stones Tuesday night and scored a decisive ratings win in the process. The show was down a good amount, however, from last year’s first show on the big stage.

FOX averaged 22.6 million viewers and a 12.8 rating/20 share in households for the night — the best of Tuesday by far, but off by more than 2 million viewers from the comparable show last year (25.2 million, 14.5/22). CBS (15.35 million, 9.6/16) was a solid second. There was a big drop from there to third-place NBC, which drew 6.8 million people and a 4.3/7. ABC (5.7 million, 3.5/6) came in fourth, and The CW (1.5 million, 1.0/2) trailed.

The story was pretty much the same in the adults 18-49 demographic. FOX dominated with an 8.0 rating but was down significantly from last year’s 9.2. CBS was the best of the rest at 3.1, followed by NBC at 2.6. ABC averaged a 2.2 and The CW a mere 0.7.
