Fast National ratings for Wednesday, November 30, 2011.
 
Led by a strong 90-minute performance for "The X Factor" and somewhat-less-impressive retention from the series premiere of "I Hate My Teenage Daughter," FOX easily won Wednesday night among young viewers and was narrowly able to hold off a surprisingly robust NBC in total viewers.
 
Among adults 18-49, FOX averaged a 3.4 rating, far ahead of second place CBS' 2.3 rating in the key demographic. NBC's 1.8 rating and the 1.7 rating for ABC followed closely, while The CW averaged a 0.8 key demo rating for the night.
 
Overall, FOX averaged an estimated 9.91 million viewers in primetime, edging out NBC's 9.72 million viewers, although NBC's 6.5 rating/10 share beat the 6.0/9 for FOX, not that that means very much. CBS was third with a 5.2/8 and 8.03 million viewers, with ABC's 3.6/5 and 5.23 million viewers good for fourth. The CW averaged 1.4/2 and 2.15 million viewers for the night.
 
[Univision averaged 3.495 million viewers and a 1.4 rating among adults 18-49 for Wednesday primetime.]

9 p.m. - Remarkably, NBC's "Harry's Law" actually won the 9 p.m. hour overall with 9.91 million viewers, though the legal drama was a distant fourth with a 1.4 key demo rating. "The X Factor" went up to 12.12 million viewers and a 4.1 rating among adults 18-49 and led into "I Hate My Teenage Daughter," which averaged 6.84 million viewers and a 2.8 key demo rating, obviously rating more admirably among young viewers than overall.
