Fast National ratings for Wednesday, May 23, 2012.
 
The finale of the 11th season of FOX's "American Idol" is likely to go down as the show's least-watched finale since 2002, but it still had plenty of juice to dominate the last night of the 2011-12 television season (and to comfortably beat the recent finales for "The Voice" and "Dancing with the Stars").
 
While "Idol" ate up the majority of the Wednesday audience, there were still enough viewers for all of ABC's finales to get variable-sized bumps.
 
[Remember with these numbers that the "Idol" finale ran though 10:07, but the last seven minutes, including the announcement of the winner, isn't part of these primetime figures for FOX, so the actual finale averages will be slightly higher than FOX's averages for primetime.]
 
For the night, FOX averaged a 6.1 rating among adults 18-49. That easily beat the combined key demographic totals for ABC (2.6 rating), CBS (1.5 rating), NBC (1.4 rating) and The CW (0.4 rating).
 
Overall, FOX averaged an estimated 20.71 million viewers and an 11.8 rating/19 share for Wednesday primetime. ABC was a distant second with 7.3 million viewers and a 4.7/8. CBS' 3.9/6 and 5.875 million viewers and NBC's 5.38 million viewers and 3.5/6 followed. The CW averaged 891,000 viewers and a 0.6/1 for the night.
 
[Univision averaged 4.95 million viewers and a 2.0 rating among adults 18-49 for Wednesday night.[
