Fast National ratings for Monday, May 21, 2012.
 
A good number of departed "House" fans returned to say farewell to the cantankerous doctor, but the FOX finale wasn't able to threaten ABC's grasp on Monday overall or NBC's less assertive hold on the night's young viewers.
 
Among other highlights from the already-repeat-filled last Monday of the season: "America's Got Talent" slipped in the second Monday of the Howard Stern Era, though that was probably related to the "Dancing with the Stars" finale bump, and while "Talent" gave "American Ninja Warrior" a sturdy lead-in, the summer reality competition squandered viewers with each half-hour.
 
For the night, NBC averaged a 2.6 rating among adults 18-49, edging out ABC's 2.5 rating and the 2.4 rating for FOX in the key demographic. CBS was a distant fourth with a 1.5 rating, while The CW averaged only a 0.2 key demo rating.
 
Overall, though, ABC won comfortably, averaging an estimated 10.63 million viewers and a 7.1 rating/11 share. FOX was a distant second with a 4.6/7 and 7.42 million viewers, nipping the 7.23 million and 4.1/7 for NBC. Fourth place went to CBS With 3.7/6 and 5.71 million viewers. The CW averaged 563,000 viewers and a 0.4/1.
