Fast National ratings for Monday, December 12, 2011.
 
Expect to see a lot more "Fear Factor" in the future, as the Joe Rogan-hosted reality series returned from its cryogenic slumber to strong ratings for NBC. Even the extreme hijinks of "Fear Factor," though, were unable to derail CBS' "2 Broke Girls" and "Two and a Half Men," which helped the network to Monday wins in all key measures.
 
Among adults 18-49, CBS averaged a 3.6 rating, beating NBC's 2.6 rating in the key demographic. FOX was third with a 1.8 rating, followed by ABC's 1.1 rating and the 0.5 rating for The CW.
 
Overall, CBS averaged an estimated 12.02 million viewers and a 7.4 rating/11 share for Monday primetime. NBC was a distant second with a 4.1/6 and 7.08 million viewers, still comfortably ahead of the 5.71 million viewers and the 3.4/5 for FOX. ABC's 2.6/4 and 4.29 million viewers finished fourth. The CW averaged preemption-fueled 1.36 million viewers and a 0.8/1.
 
[Univision averaged 3.35 million viewers and a 1.4 rating among adults 18-49 for Monday primetime.]
