TV Ratings: ‘Big Bang Theory’ crushes ‘American Idol’ on Thursday, while ‘Do No Harm’ tanks

Fast National ratings for Thursday, January 31, 2013. 
“American Idol” had its first head-to-head meeting of the season with a new “Big Bang Theory” and the results weren’t close. The CBS comedy crushed “American Idol” in all measures, helping the network to ratings wins on Thursday night.
On a busy night, NBC saw “30 Rock” get a reasonably large finale bump (by recent “30 Rock” standards), but “Do No Harm failed immediately and dramatically. Meanwhile, ABC’s “Scandal” approached series highs once again and The CW got a very strong night out of “The Vampire Diaries,” as lots and lots of people were watching TV on Thursday.
Among adults 18-49, CBS averaged a 3.4 rating, nipping the 3.3 rating for FOX in the key demographic. ABC’s 2.2 rating was third, followed by NBC’s 1.6 rating and the 1.0 key demo rating for The CW.
Overall, CBS had a bit more breathing room with 14.01 million viewers and an 8.7 rating/14 share, comfortably beating the 5.7/9 and 9.63 million viewers for FOX. ABC was third on the night with 7.15 million viewers and a 4.9/8, followed by the 2.6/4 and 4.05 million viewers for NBC. The CW averaged a 1.3/2 and 2.15 million viewers for Thursday night.
