Fast National ratings for Wednesday, December 18, 2013.
 
Viewers weren't hugely fascinated by ABC's broadcast of "Barbara Walters: The 10 Most Fascinating People of 2013," but they were at least vaguely interested, as the special was a sluggish Wednesday's top show in most key measures, leading the network to ratings wins.
 
Without any assist from "The Voice," NBC's "The Sing-Off" slipped somewhat, but still beat "The X Factor" and outdid NBC's latest Michael Buble Christmas special, which was in line with last year's weak performance. And speaking of specials that never draw big ratings, at some point CBS' has to cut ties with the "Home For The Holidays" series, which has positive aspirations, but draws astoundingly low ratings every year, falling even lower this year.
 
Meanwhile, The CW finally got OK numbers for an IHeart Radio special, as the "Jingle Ball 2013" telecast outdrew the network's various album release specials.
 
On to the numbers...
 
Among adults 18-49, ABC averaged a 1.8 rating for Wednesday primetime, beating NBC's 1.5 rating in the key demographic. FOX was third with a 1.3 key demo rating, beating CBS' 1.0 rating and the 0.6 key demo rating for The CW.
