Fast National ratings for Friday, December 5, 2014.

The Friday pecking order was a little strange this week, as "Shark Tank" led ABC to a rare overall win for the night, made possible by CBS' unimpressive "A Very Grammy Christmas" special, but FOX's coverage of the Pac-12 football championship was good for a key demo win.

Among other Friday notables, "Grimm" and "Constantine" were both down for NBC, while "The Amazing Race" was up for CBS. There was a sizable gap between performances for ABC's "Last Man Standing" and "Cristela," while NBC's "How Murray Saved Christmas" had a soft premiere.

On to the numbers...

Among adults 18-49, FOX averaged a 1.6 rating for Friday night, topping ABC's 1.4 rating in the key demographic. CBS and NBC were third with a 0.9 key demo rating, followed by The CW's 0.4 key demo rating for the night.

Overall, though, ABC's 6.35 million viewers and 4.1 rating/7 share led Friday primetime, edging out CBS' 5.81 million viewers and 3.7/7.
