Fast National ratings for Thursday, April 11, 2013.
For the second straight night, "American Idol" was up week-to-week, as FOX cruised to Thursday victories against repeat-heavy programming on ABC and CBS. 
NBC, also airing originals on Thursday, got week-to-week gains for "Community" and "The Office," while "Parks and Recreation" and the "Go On" finale were flat. Also flat was "Hannibal," which is a more encouraging sign for a show in its second week.
For the night, FOX averaged a 2.7 rating among adults 18-49, topping CBS' 1.9 rating in the key demographic. NBC's 1.5 rating and ABC's 1.2 rating followed, while The CW averaged a 0.3 key demo rating.
Overall, FOX averaged an estimated 9.77 million viewers and a 6.0 rating/9 share for Thursday primetime, topping CBS' 5.7/9 and 8.99 million viewers. There was a big drop to ABC's 2.9/5 and 4.19 million viewers and NBC's 3.53 million viewers and 2.3/4. The CW averaged 942,000 viewers and a 0.7/1.
