Fast National ratings for Monday, November 7, 2011.
 
It was a bounce-back Monday for many primetime favorites, as FOX, CBS and ABC were all up after Halloween sluggishness last week. While FOX got the most encouraging bumps with "Terra Nova" and "House," the basic order of things didn't change, as CBS dominated Monday among young viewers and ABC ruled overall.
 
Among adults 18-49, CBS averaged a 4.0 rating, comfortably topping the 3.1 rating for ABC in the key demographic. FOX was third with a 2.7 rating, with a big drop to NBC's 1.3 rating. The CW averaged a 0.6 rating for the night.
 
Overall, though, ABC averaged 15.77 million viewers and a 10.4 rating/16 share, easily winning the night. CBS was a distant second with a 7.1/11 and 11.35 million viewers, followed by another big drop to FOX's 4.5/7 and 7.61 million viewers and then another big drop to NBC's 2.6/4 and 3.97 million viewers. The CW did a 0.9/1 and 1.33 million viewers in primetime.
