After being walloped in the February sweeps and falling to fifth place behind Univision, NBC has taken another hit. With last week’s ratings in, the network has fallen to third place among broadcasters for the full 2012-2013 season. The returns for the week ending March 10 have Fox bouncing up to second place overall season-to-date with a 2.6/7 over NBC’s 2.5/7. With the Super Bowl, the Grammys and a strong schedule of The Big Bang Theory and the NCIS franchise, CBS claims the top spot with 3.1/9. Oscars broadcaster ABC is fourth with a 2.3/6 and the CW a far fifth with a 0.7/2. This is the first time Fox has been in the second spot this season since the September 24 Week 1. CBS is even with its ratings for the 2011-2012 season year-over-year, while NBC is down 7%, ABC -8%, the CW -13% and Fox -21% from last season, when it held the No. 1 spot.

It wasn’t always so bleak for NBC this season. Coming off a solid chest-thumping fall and topping the November sweeps fueled by The Voice and football, the network was in the top spot for the season up until the week ending January 27. But after those shows ended came quickly cancelled duds like Do No Harm, weak freshman comedy 1600 Penn and the dismal return of Smash. On the horizon, The Voice returns for a new season March 25 and solid newbie Revolution also is coming back.

For the week, with strong showings from three live American Idol broadcasts, its Sunday animation block, a surging Glee, freshman The Following and Bones, Fox dominated among adults 18-49. The network got a 2.3/7 and its programs took eight of the top 20 spots. CBS also had eight shows (including Big Bang Theory and Two And A Half Men in the No. 1 and No. 2 spots) in the Top 20, but it drew a 1.9/5. Both networks were down ratings-wise from the comparable week last year 4% and 5% respectively. ABC got a 1.5/4 for the week, down 6% in the ratings from the week of March 5, 2012. NBC came in fourth place for the week with a 1.1/3. That’s a cratering of 39% from the 1.8 rating the network drew a year ago during the week of March 5.
