Fast National ratings for Tuesday, November 10, 2009.
 
In its premiere last week, ABC's "V" shocked some observers by beating out CBS' dominant "NCIS" in the 18-49 demo. That advantage lasted all of one episode, as "NCIS" reclaimed its Tuesday superiority and CBS held onto its dominant position adopt the night.
 
That doesn't mean, by the way, that "V" went into the tank in Week Two. It just means that when people complain that only old people watch "NCIS," they're wrong.
 
Among adults 18-49, CBS averaged a 3.5 rating, which ABC's 3.2 rating and the 3.1 rating for NBC close behind. FOX's 2.3 rating was good for fourth, while The CW's 0.9 rating trailed.
 
Overall, it was a larger margin-of-victory, as CBS averaged an estimated 16.43 million viewers to go with a 10.3 rating/16 share. ABC was well back in second with a 7.6/12 and 11.89 million viewers on average. NBC was third with a 5.1/8, while FOX's 3.5/5 was fourth. The CW was fifth with a 1.2/2.
 
In the 8 p.m. hour, CBS' "NCIS" averaged a 12.3/19, pulling in nearly 20.2 million viewers and doing a 4.2 rating in the demo.

NBC's "Biggest Loser" was third, beating the 3.8/6 for the first hour of FOX's "So You Think You Can Dance." The CW's "90210" had a 1.5/2, up very slightly from last week.
 
CBS stayed on top at 10 p.m. with a 10.0/15 for "NCIS: Los Angeles," which nipped the 9.9/15 for "Dancing with the Stars" on ABC.
