Fast National ratings for Monday, May 7, 2012.
 
After NBC dropped from first among young Monday viewers last week, "The Voice" got a bit of a finale bump and helped the network reclaim that crown. ABC still easily won Monday overall, thanks to "Dancing with the Stars" and a "Castle" finale bump.
 
Meanwhile, a highly competitive 8 p.m. hour led to only so-so numbers for CBS' hour-long "2 Broke Girls" finale and to almost "L.A. Complex"-low numbers for The CW's "Gossip Girl."
 
For the night, NBC averaged a 3.1 rating among adults 18-49, edging out CBS' 2.9 rating in the key demographic. ABC's 2.6 rating and the 2.0 rating for FOX followed, while The CW did a 0.5 key demo rating for the night.
 
Overall, though, ABC won easily with an estimated 14.85 million viewers and a 9.6 rating/15 share.
