Fast National ratings for Monday, February 7, 2011.
 
FOX got a somewhat disappointing, but hardly disastrous, premiere for the heavily promoted drama "The Chicago Code," which dropped a substantial number of young viewers from a strong new episode of "House." That 9 p.m. droop, coupled with the usual power of "Two and a Half Men" and "Mike & Molly," allowed CBS to escape with a pair of narrow Monday wins.
 
Among adults 18-49, CBS averaged a 3.5 rating, nipping the 3.4 rating for FOX in the key demographic. ABC was third with a 2.9 rating, far ahead of the 1.6 rating for NBC and the 0.8 rating for The CW.
 
Overall, CBS averaged an estimated 11.53 million viewers and a 7.1 rating/11 share. Again, FOX was a close second with a 6.5/10 and 10.86 million viewers. ABC's 6.2/10 and 9.58 million viewers finished an OK third. NBC was a distant fourth with a 3.8/6 and 6.37 million viewers, still comfortably ahead of the 1.705 million viewers and 1.2/2 for The CW.
 
8 p.m. - FOX started primetime in first with 12.32 million viewers and a 4.3 rating among adults 18-49 for "House." CBS was a solid second with a Katy Perry-barely-boosted "How I Met Your Mother" (10.1 million and a 3.8 demo rating) and "Rules of Engagement" (9.48 million and a 3.2 demo). ABC's "The Bachelor" was a close third with 9.5 million viewers and a 3.0 demo rating. NBC's "Chuck" averaged 5.42 million and a 1.7 demo rating, low for the season, but steady with last week. The CW's "90210" averaged 1.78 million viewers and a 0.9 demo.
 
9 p.m. - CBS stormed into first in the 9 p.m. hour with "Two and a Half Men" (15.13 million and a 4.4 demo rating) and "Mike & Molly" (12.74 million and a 3.6 demo). ABC's "The Bachelor" moved up to second with 9.97 million. The series premiere of "The Chicago Code" averaged 9.4 million viewers and a 2.4 rating in the key demo, obviously squandering a lot of its lead-in, though only falling a little at the half-hour point. NBC's pre-deceased "The Cape" averaged 4.56 million viewers and a 1.3 demo rating in its steady slide. "Gossip Girl" had 1.63 million viewers for The CW.
 
10 p.m. - "Hawaii Five-0" averaged 10.855 million viewers and a 2.8 demo rating to win the competitive 10 p.m. hour. ABC's "Castle" averaged 9.26 million and a 2.5 demo rating. In its first airing against originals on both ABC and CBS, NBC's "Harry's Law" slid to 9.14 million viewers and a 1.7 demo rating, though it was the only 10 p.m. show to increase its audience in the second half of the hour.
