Fast National ratings for Monday, September 22, 2014.

Even airing outside of its normal Thursday home, "The Big Bang Theory" had a huge launch on Monday, combining with a strong premiere for "Scorpion" to help CBS snatch the Monday ratings crown from NBC, at least overall.

"Big Bang Theory" helped push "The Voice" to a relatively low fall launch, though "Blacklist" returned with big numbers to dominate the "Under the Dome" finale and carry NBC to a win among young viewers.

Over on FOX, the exhaustively promoted premiere of "Gotham" did reasonably big numbers, especially in the key demo, but the return of "Sleepy Hollow" after a nine-month absence was somewhat soft. 

Finally, the night's other major debut was ABC's sneak of "Forever," which drew well below the normal "Castle" ratings for its time period.

Stay tuned for more analysis later when Final Live+Same Day ratings become available.
