Fast National ratings for Wednesday, December 4, 2013.
 
A heavily promoted episode of "Survivor: Blood vs. Water" drew a season-high audience for CBS and led the network to an overall win on Wednesday, but a pair of holiday-themed specials, including "Saturday Night Live Christmas" gave NBC a win among young viewers.
 
Like "Survivor," "The X Factor" aired last week to pre-Thanksgiving lows and bounced back a tiny bit, albeit not to the same level.
 
The CW drew a large audience and good demos for the introduction of the proto-Flash on "Arrow" and also got a little bump for "The Tomorrow People."
 
Finally, it was a low night for ABC's comedies, but "Nashville" was steady.
 
On to the numbers...
