Fast National ratings for Monday, April 1, 2013.
 
"The Voice" held onto most of its spring return audience to carry NBC to a commanding Monday win among young viewers, but at least some of the network's joy may be tempered by declines for "Revolution" in its second airing of 2013.
 
Meanwhile, FOX's "The Following" also continued a gradual decline, even though its "Bones" lead-in was up week-to-week. In contrast, ABC's "Castle" overcame a drop for its "Dancing with the Stars" lead-in and got a 100th episode bump.
 
For the night, NBC averaged a 3.9 rating among adults 18-49, far ahead of ABC's 2.2 rating in the key demographic. FOX was a close third with a 2.1 key demo rating, followed by CBS' 1.2 key demo rating and the 0.3 key demo rating for The CW.
 
Overall, though, ABC topped Monday night with 13.1 million viewers and an 8.4 rating/13 share, easily topping NBC's 10.93 million viewers and 6.5/10. FOX was third with a 4.2/6 and 6.72 million viewers, with CBS' 4.8 million and 3.1/5 taking fourth. The CW averaged a 0.5/1 and 792,000 viewers for Monday.
