Fast National ratings for Thursday, April 12, 2012.
 
Without CBS originals on Thursday night, FOX's "American Idol" took a big jump and "Touch" stopped weeks of declines, as the network controlled primetime in all key measures.
 
The absence of new CBS episodes also helped ABC's "Scandal" avoid a post-premiere decline and even led to "Community" and "Awake" gaining a few viewers.
 
Among adults 18-49, FOX averaged a 3.2 rating for Thursday night, winning the key demographic. CBS was still second with a 2.4 rating, followed by ABC's 2.1 rating. NBC averaged a 1.3 rating, while The CW's repeats posted a 0.4 key demo rating.
 
Overall, FOX averaged an estimated 11.78 million viewers to go with a 7.3 rating/12 share. CBS was second with a 5.5/9 and 8.83 million viewers, just ahead of ABC's 5.4/9 and 8.055 million viewers. There was the usual big drop to NBC's 2.0/3 and 3.17 million viewers. The CW averaged a 0.8/1 and 961,000 viewers.
