    Remove football from the ratings and the networks (other than the CW) are remarkably close.

    It’s funny; after all the talk about how badly NBC was doing this year, they were only down 4% in the 18-49. That’s just a hair more than CBS (3%), and a lot less than ABC, FOX, or the CW who were each down 12, 22, and 13% respectively.

    Of course, good numbers from The Voice certainly helped, but still.

    Wow, NBC only 0.1 behind Fox for second.

    With a fall schedule that is stronger than what made it No. 1 last fall and the Winter Olympics, NBC has a shot at finishing No. 2 next season. Fox has the Super Bowl, which will certainly help.

    I wanna see numbers from 10 years ago for comparison sake

    Football and The Voice help NBC a lot, I know. But Fox only won for so many years because of two (sometimes three) nights of American Idol a week. If you take out the Championship Game, Super Bowl, Survivor, and The Amazing Race (Sports and reality competitions) CBS would be down too. Take out Saturday Night Football, Dancing with the Stars, The Bachelor, and Shark Tank ABC is down. If you take out Saturday Night Football, The X Factor, American Idol, Hell’s Kitchen, and Kitchen Nightmares FOX is down. If you take out awards show too it gets worse. No Grammy’s or CMA’s for CBS, no Golden Globes for NBC, no Oscar’s or Billboard Awards for ABC. The thing is that all the networks have reality shows, sports, and awards shows that boost the ratings.

    This may be a stupid question, but the ratings are “averaged” over what time period? Is this their primetime hourly average, is it a weekly primetime average, or what? CBS has averaged 11.8 million viewers, but is that per primetime week (total up all the viewers and divide by the 34 weeks of the season), per primetime night (total viewers divided by 238 days), per primetime hour (total viewers divided by 714 – 238 days times 3 primetime hours). Which is it, or is it some other super secret formula?

    It looks like you merged together zap2it and tv by the numbers and no longer show the actual ratings from nielson. I hate how it is now and won’t come here anymore.
