Fast National ratings for Sunday, December 15, 2013.
 
NBC's Sunday Night Football showdown between the Steelers and Bengals helped the network to an overall win on Sunday night, but NFL overrun and a strong showing by "Family Guy" helped FOX eke out a slim win among young viewers.
 
There was a lot of competition on Sunday night, with CBS' "Survivor: Blood vs. Water" finale doing OK numbers and leading to a drop for "Once Upon a Time." We'll have to stay tuned for cable numbers as well, particularly the drama finales on Showtime.
 
Note, of course, that FOX had NFL overrun and CBS also had chunks of NFL overrun in several markets, so nearly all of these numbers are likely to shift a bit.
