TV Ratings Thursday: American Idol, Grey’s Anatomy hit season lows, Perfect Couples is done

No idea why everything last night was having trouble luring viewers (perhaps everyone was watching the Lakers/Celtics game?) but several shows hit season or series lows.

“Grey’s Anatomy” drew its lowest rating of the season with a 3.9 in the 18-49 demo. “Private Practice” was actually up a tick to a 2.7.

“American Idol” was down to a 7.2 in the demo, its lowest ratings of the season. It’s still a behemoth, but its looking like the show may dip in the high 5.0 realm before the seasons through–and that would be showing a God can bleed. “Bones” drew a 3.3, a much higher number than “Human Target” the night before, which came out of a much higher demo from American Idol; proving again why its likely “Human Target” will be cancelled.

The NBC comedies were typical of NBC. “The Office” was typically strong, “Parks and Rec” was down but continues its upward trend indicating a likely renewal, while “30 Rock” was about even with its ratings trend. After a better start in the new year, “Community” has fallen back, and its 1.8 rating isn’t quite to definite cancellation, but it doesn’t look good.

On CBS, its looking increasingly likely that “$#!* My Dad Says” won’t come back for a second season. And with “CSI” continuing to trend down, the show is likely about one season removed from cancellation–unless CBS gutsily decided to cancel it this year.
