Fast National ratings for Sunday, October 6, 2013.
 
The end of a high-scoring thriller between the Broncos and Cowboys spread 44 minutes into primetime and helped boost CBS to a comfortable overall win on Sunday, while coverage of the Houston-San Francisco Sunday Night Football game put NBC in first among young viewers.
 
Without any football overrun, FOX still got a solid performance for the annual Treehouse of Horrors episode of "The Simpsons," as well as a new "Family Guy," though it's hard to compare this week's performances to last week's football-boosted premieres. 
 
Similarly, comparing this week's non-football CBS numbers to last week's premieres probably isn't helpful, especially since CBS also aired the NFL Network's late game in San Diego.
 
It's easier to compare ABC's Sunday to premiere levels, where we can see that "Once Upon a Time" posted only a small drop among young viewers -- total retention among adults 18-34, ABC boasts -- while the declines for "Revenge" and particularly "Betrayal" were steeper.
