Fast National ratings for Monday, October 8, 2012.
There was lots of good news on Monday night, as "The Voice" and "Dancing with the Stars" both saw week-to-week growth and helped carry NBC and ABC to their regular Monday split.
Also seeing Monday growth were CBS' "Mike & Molly," "Hawaii Five-0" and the endangered "Partners," plus ABC's "Castle."
The news was less good for FOX's troubled "The Mob Doctor" and The CW's impressively low-rated premieres for "90210" and the final season of "Gossip Girl."
Also down a tiny bit was NBC's "Revolution," though the freshman hit posted its smallest drops yet, which either does or doesn't count as an achievement given that its lead-in continues to rise.
Anyway... On to the numbers...
Among adults 18-49, NBC comfortably won Monday night with a 4.2 rating, far ahead of the 2.8 rating for CBS in the key demo graphic. ABC was third with a 2.2 key demo rating, beating FOX's 1.4 key demo rating. The CW averaged a 0.4 key demo rating for the night.
Overall, though, ABC averaged an estimated 12.41 million viewers and an 8.2 rating/12 share, beating NBC's 6.5/10 and 11.12 million viewers. Both networks were up from last week, but ABC still expanded its overall margin-of-victory. CBS was third with a 5.3/8 and 8.67 million viewers, far ahead of FOX's 3.2/5 and 5.27 million viewers.
