Fast National ratings for Thursday, April 5, 2012.
 
All of your favorite shows were down on Thursday night. You name it, it dropped, either in overall viewership or young viewership on a sluggish evening that was won by CBS overall and FOX in the key demographic. 
 
In addition to falls for shows like "American Idol," "The Big Bang Theory," "Grey's Anatomy," "Community" and "Touch," ABC only got a so-so premiere from the new drama "Scandal," which retained decently from "Grey's Anatomy," but won't instantly make the network forget "Private Practice."
 
Among adults 18-49, FOX averaged a 3.0 rating for Thursday night, edging out CBS' 2.9 rating in the key demographic, though of course CBS won the 8-10 p.m. portion of primetime actually shared by both networks. ABC was third with a 2.1 rating, followed by NBC's 1.1 rating and the 0.4 rating for The CW.
 
Overall, though, CBS won the night easily with 12.28 million viewers and a 7.5 rating/13 share. FOX was second with a 6.5/11 and 10.62 million viewers, far ahead of ABC's 5.1/9 and 7.56 million. NBC averaged a dismal 2.69 million viewers and a 1.8/3 for Thursday primetime, at least beating The CW's 964,000 and 0.6/1 for repeats.
 
[Univision averaged 3.57 million viewers and a 1.4 rating among adults 18-49 for Thursday night.]

ABC was second with 8.075 million viewers and a 2.8 key demo rating for a low-rated episode of "Grey's Anatomy."
