Fast National ratings for Monday, October 15, 2012.
 
NBC's "Revolution" halted its post-premiere slippage and combined with "The Voice" to given NBC yet another Monday night rout among young viewers. ABC's "Dancing with the Stars" and "Castle" also added viewers and helped that network maintain its usual overall win.
 
Meanwhile, FOX got an unimpressive performance from the National League Championship Series and The CW's "Gossip Girl" failed to build on last week's dismal premiere, though "90210" was up.
 
[Note: As was the case last week, CBS had the Monday Night Football game in one market. Since that market was San Diego, though, it's even harder to anticipate the impact of that NFL inflation.]
 
Among adults 18-49, NBC averaged a 4.3 rating for Monday night, far ahead of CBS' 2.6 rating in the key demographic. ABC's 2.1 rating was good for third, beating FOX's 1.3 rating and the 0.5 key demo rating for The CW.
 
Overall, though, ABC won the night with 12.6 million viewers and an 8.4 rating/13 share. NBC was second with a 6.7/10 and 11.47 million viewers, far ahead of the 5.1/8 and 8.23 million viewers for CBS.
