Fast National ratings for Monday, November 9, 2009.
 
ABC's "Dancing with the Stars" continued its Monday dominance in total viewers, while FOX was able to claim the key demographic thanks to a solid return from the recently absent "House."
 
Among adults 18-49, FOX earned a 4.0 rating, nipping the 3.9 rating for CBS in the key demo. ABC's 3.2 rating was good for a close third, far ahead of the 1.8 rating for NBC and The CW's 1.2 rating.
 
Overall, though, ABC averaged an estimated 15.33 million viewers and a 9.7 rating/15 share for a dominant win. CBS was a distant second with a 7.5/12 and 11.89 million viewers. FOX's 5.9/9 and 10.13 million viewers came in third. NBC was far back again with a 3.2/5, still bettering the 1.6/2 for The CW.
 
ABC controlled the 8 p.m. hour with an 11.0/16 for "Dancing with the Stars." FOX's "House" was second with a 7.4/11 overall, but the medical drama's 5.1 demo rating was the night's best. CBS' "How I Met Your Mother" and "Accidentally on Purpose" averaged a 5.3/8 for third. NBC's "Heroes" had a 3.4/5 and a 2.3 demo rating, both down. The CW's "One Tree Hill" improved from last week and was on the high side of its season averages.
 
At 9 p.m. ABC stayed on top with an 11.3/17 for "Dancing with the Stars." CBS' "Two and a Half Men" (8.7/13) and "The Big Bang Theory" (7.7/12) were second overall and won the hour with a 4.5 demo rating, with "Big Bang Theory" holding a slim advantage over its lead-in. FOX's "Lie to Me" lost much of the "House" audience, slipping to a 4.4/7 and a 3.0 demo rating. The CW's "Gossip Girl" had a 1.5/2 for the week and a 1.2 demo rating, both up from last week, which either had something to do with the much-vaunted threesome, or else it didn't. [Note that "Gossip Girl" was certainly up from last week. Noticeable. However, that "up" just returned the show to where its ratings were two weeks ago. Last week? FOX aired the World Series, featuring the New York Yankees, which may have had some impact on a Gotham-centric show.]
 
In the 10 p.m. hour, CBS' "CSI: Miami," the first part of a three-"CSI" crossover, had an 8.9/15 and a 4.0 demo rating, both dominant for the hour.  "Castle" was up from last week. Meanwhile, "The Jay Leno Show" averaged a 2.6/4 and 3.97 million viewers, along with a 1.2 demo rating. Those aren't good numbers for NBC.
