Ratings: Only CSI, Happy Endings Gain in Demo; Idol Drops 16%; No Tree Hill Boost from the Chad

Happy Endings and CSI were the only programs to notch demo gains this Wednesday, while Chad Michael Murray’s Tree Hill homecoming failed to rouse the swan-songing CW sudser’s numbers.

Leading out of Modern Family (which was flat with 11.5 million total viewers and a 4.7 demo rating), Happy Endings drew 5.7 mil while scoring a 2.5, up a few percentage points week-to-week.

CSI dominated the 10 o’clock hour with 11.8 million total viewers and a 2.8 rating, good for gains of 6 and 8 percent.

Among the night’s conspicuous declines, American Idol‘s Top 24 Reveal: Part 1 drew 15.9 million total viewers and a 5.1 rating, down 16 percent versus last Wednesday. And while it’s becoming increasingly irrelevant to note Idol‘s year-over-year drops, the Fox hit was down some 30 percent from Season 10’s Top 24 christening.

Elsewhere….

8 pm | Survivor: One World (10.3 mil/2.8) dropped 10 percent in the demo to a new series low. ABC’s sitcombo of The Middle (7.5 mil/2.3) and Suburgatory (6.8 mil/2.3) each slipped to season lows. NBC’s Whitney (4.1 mil/1.5) was down 8 and 12 percent, while Chelsea (3.4 mil/1.3) dipped a tenth in the demo to a new low. One Tree Hill (1.37 mil/0.7) lost a handful of eyeballs and was down a tenth in the demo.

9 pm | Criminal Minds led the hour with 12.6 million total viewers (up 4 percent) and a 3.1 rating. Modern Family held steady at 11.5 mil/4.7. NBC’s Rock Center dropped 10 percent to 2.7 mil/0.6.

10 pm | Trailing far behind CSI, Law & Order: SVU (5.9 ml/1.6) dipped a tenth in the demo. 20/20‘s “Before They Were Famous” Oscars special only found 4.8 million people caring.
