Fast National ratings for Thursday, January 16, 2014. 
 
FOX won Thursday night in all measures thanks to the second night of "American Idol," but it was really an evening characterized by ugly drops.
 
"American Idol" dipped night-to-night in all measures in its Thursday premiere -- 13 percent in viewers and 19 percent in young viewers -- and, in fact, lost to a "Big Bang Theory" repeat overall (it topped the "Big Bang Theory" repeat among young viewers, but not by much).
 
Those numbers are ugly, but they may not be as ugly as what NBC is facing with "The Michael J. Fox Show," which slipped to only 2 million viewers and an astonishingly low 0.6 key demo rating. But, hey, "Parks and Recreation" was NBC's top comedy in the key demo, while "Community" was its top comedy overall, even if both were down from last week."
 
Finally, a "Shark Tank" repeat easily improved on "The Assets" among young viewers.
 
On to the numbers.
 
Among adults 18-49, FOX averaged a 3.8 rating for Thursday night, tops in the key demographic. That beat the combined totals for CBS (1.5 rating), plus ABC and NBC (1.0 rating apiece), but not the combined total if you include The CW's 0.4 key demo rating.
 
Overall, FOX averaged an estimated 13.18 million viewers and a 7.5 rating/12 share for Thursday. CBS was second with 7.22 million viewers and a 4.5/7. There was a huge drop to ABC's 3.35 million and 2.3/4 and NBC's 3.14 million and 2.1/3. The CW averaged a 1.4/2 and 1,955 million viewers.
