Fast National ratings for Sunday, October 21, 2012.
 
ABC was the only network unimpacted by live sporting events on Sunday night and saw growth for all of its dramas, but primetime was dominated by NBC's Sunday Night Football game and by CBS' early evening NFL overrun.
 
Sunday's third big sporting event was FOX's National League Championship Series Game 6, which couldn't lift the network out of fourth.
 
For the night, NBC averaged a 4.8 rating among adults 18-49, beating the 3.8 rating for CBS in the key demographic. ABC was third with a 2.3 key demo rating, followed by the 1.6 rating for FOX.
 
Overall, though, CBS averaged an estimated 14.485 million viewers and a 9.2 rating/14 share for Sunday night, beating the 12.78 million viewers and 7.8/12 for NBC. ABC was third with a 4.5/7 and 7.3 million viewers, topping the 3.5/5 and 5.66 million viewers for FOX.
