CBS won Friday night both in the 18-49-year old demo and total viewers. ABC, with reruns of three shows shown earlier in the week, "Modern Family," "Cougar Town" and "FlashForward," along with the season premiere of "20/20," came in second in 18-49-year-olds, but third in overall viewers.
NBC’s lineup of the 20th (!) season premiere of "Law & Order," "Dateline" (with a big Michael Jackson hook), and "The Jay Leno Show" was good for second in overall viewers, but only third in 18-to-49-year-olds.
Fox struggled with the season premieres of "Dollhouse" and "Brothers," as did the CW with the season premiere of "Smallville" and a repeat of "America’s Next Top Model." Fox came in fourth for the night in both 18-to49-year-olds and total viewers, and the CW came in last in both categories.
TVByTheNumbers has all these numbers.
