TV Ratings: Fox Wins November Sweep Among Adults 18-49
The dust has settled on November's annual ratings battle, and Fox comes out on top for only the second time in the network's history.
According to Nielsen ratings for Oct. 28 through Nov. 23, Fox averaged a 3.1 rating among adults 18-49. That marks a 9 percent lead over its nearest competitor, CBS, which averaged a 2.8 rating.
Fox's score marks a 15 percent improvement with the key demographic over the same period last year, where it tied with CBS for a joint win of 2.7 in adults 18-49. (In 2009, Fox earned its only previous solo November sweeps victory in the demo.)
ABC was down 4 percent from 2010 for a third-place rating of 2.5 among the demo, followed by NBC, which posted the same score (2.4) two years running.
Among total viewers, CBS boasted its 11th straight November win. The network averaged 11.43 million for the period, a 3 percent gain from 11.13 million in 2010.
Fox posted the biggest gains year-over-year, with 11 percent growth and an average audience of 8.64 million, but it was topped by ABC.
ABC dropped 4 percent from 2010 to an average audience of 9.28 million.
NBC lost 5 percent of its audience from the previous year, averaging 6.86 million viewers.
