Fast National ratings for Monday, December 28, 2009.
 
Maybe most television viewers were watching a Monday Night Football thriller on ESPN, but Monday proved to be the sort of ratings night on which ABC very nearly won the key demographic on the strength of a bloated "Pirates of the Caribbean" sequel.
 
Among adults 18-49, CBS averaged a 2.3 rating, nipping the 2.0 rating for ABC in the all-important age range. FOX was third with a 1.5 rating, with NBC's 1.0 rating and the 0.3 rating for The CW trailing.
 
Overall, CBS was in a bit more control, averaging an estimated 8.21 million viewers and a 5.0 rating/8 share. ABC was second with a 3.6/6 and an estimated viewership of 6.25 million viewers. FOX's 3.0/5 was third, with NBC's 1.6/3 a distant fourth. The CW finished fifth with a 0.6/1.
 
In the 8 p.m. hour, CBS averaged a 3.7/6 for repeats of "How I Met Your Mother" and "Accidentally on Purpose." In terms of ratings, ABC's "Pirates of the Caribbean: At World's End" was second with a 3.6/6, but the movie won the hour in viewers (6.1 million) and in the key demo (1.8 rating). FOX' repeat of "House" had a 3.0/5 for third. NBC finished fourth with a 1.8/3 for two repeats of "Community." The CW's "One Tree Hill" repeat was fifth.
 
CBS' "Two and a Half Men" and "The Big Bang Theory" repeats delivered a 6.4/10 in the 9 p.m. hour, also winning in the key demo with a 2.9 rating. ABC's movie stayed second with a 3.6/6. FOX finished third with a 2.9/5 for a "Lie to Me" repeat. A second two-episode "Community" block slipped for NBC. Fifth went to The CW's "Gossip Girl" repeat, which had a 0.5/1.
 
"CSI: Miami" helped CBS close the night in first, doing a 6.1/10 for a repeat. ABC's movie was second overall and tied for first in the key demo. A repeat of "The Jay Leno Show" did a 2.1/4 for third, but still drew 3.2 million viewers.
