Fast National ratings for Monday, Oct. 12, 2009.
 
With strong performances from its 9 p.m. comedy block and from "CSI: Miami," CBS was able to narrowly win Monday night in the key demographic, but ABC scored a more convincing win overall, thanks to "Dancing with the Stars."
 
And yes, that sounds a lot like every Monday night. Look, we'd love to report more exciting ratings news if there were any.
 
Among adults 18-49, CBS averaged a 4.0 rating, nipping the 3.9 rating for FOX. ABC's 3.1 rating was a solid third in the key demo. NBC was fourth with a 1.9 rating, beating the 1.2 rating for The CW.
 
Overall, though, ABC averaged an estimated 14.3 million viewers to go with a 9.3 rating/14 share. CBS was second with a 7.2/11, topping the 6.1/9 for FOX. NBC was a distant fourth with a 3.4/5, followed by the 1.6/2 for The CW.

CBS' "How I Met Your Mother" and "Accidentally on Purpose" averaged a 5.2/8 between them. NBC's "Heroes" was fourth with a 3.5/5 and a 2.4 rating in the key demographic.
