Fast National ratings for Thursday, January 30, 2014.
 
In their first head-to-head meeting of the season, "The Big Bang Theory" crushed "American Idol" as CBS rolled to primetime wins in all measures.
 
Among several Thursday notables, NBC's "Community" was able to withstand the new "Big Bang" episode, basically duplicating last week's ratings, which weren't exactly great, but sometimes you have to take good-ish news with grains of salt. "Parks and Recreation" was also stable with last week.
 
Meanwhile, "Rake" took a big drop in its second week, proving to be particularly weak in the young demos that have traditionally been the bread and butter for its "American Idol" lead-in.
 
Finally, "The Vampire Diaries" was down a hair for The CW, but "Reign" was flat week-to-week, with counts as good news for that network.
 
On to the numbers...
 
Among adults 18-49, CBS averaged a 2.6 rating for Thursday night, topping FOX's 2.2 rating in the key demographic. NBC was third with a 1.6 key demo rating, followed by ABC's 1.0 key demo rating and The CW's 0.8 key demo rating for the night.
