Fox hasn’t been able to successfully launch a comedy series behind American Idol. Can The X Factor do the trick? Results from last night’s debut of new multicamera comedy I Hate My Teenage Daughter after the singing competition are inconclusive. The sitcom drew a 2.8/7 in adults 18-49. That was down 20% from the last comedy to launch behind Idol, last spring’s Breaking In. (That series ended up being canceled by the network before getting miraculously resurrected over the summer.) Of course, Breaking In had a stronger lead-in from Idol (6.8 demo rating) than IHMTD had from X Factor (3.7/10), which was even with its last Wednesday edition two weeks ago and up 16% from the Tuesday outing last week. With ABC’s lineup led by megahit Modern Family (2.6/7) in repeats and CBS off-pattern, Fox (3.4/9, 9.9 million) won the night in 18-49 and total viewers. Meanwhile, ABC’s Happy Endings (2.1/5) scored its best repeat numbers.

CBS’ Survivor: South Pacific (3.1/9) was down 6% from its last regular telecast two weeks ago. Following a Criminal Minds repeat (2.1/5), the Grammy Nominations Concert special (1.9/5) was up 12% from last year’s telecast. NBC’s annual Christmas In Rockefeller Center (1.8/5) was down 5% from last year’s telecast. The network’s dramas took full advantage of ABC airing repeats and CBS airing the Criminal Minds rerun and Grammys special from 9-11 PM. Harry’s Law (1.4/3, 9.9 million) was up 27% in 18-49 from its last original two weeks ago to hit season highs in both 18-49 and total viewers. Law & Order: SVU (2.2/6, 9.9 million) was up 16%, posting a season high in total viewers. The CW logged its most-watched Wednesday this season with a Muppets Christmas special (2.4 million, 0.8/2 in 18-49) and a new America’s Next Top Model (1.9 million, 0.8/2)
