Fast National ratings for Thursday, September 18, 2014.

Testing the limits of America's insatiable appetite for NFL action, a dismally one-sided Thursday Night Football game between the Falcons and Buccaneers fell hard from last week's telecast, though CBS still dominated primetime in all measures.

The game, which was essentially over by the end of the first quarter, was off by 40 percent from the Fast Nationals for last week's Thursday Night Football premiere.

Thursday's only other original programming was NBC's "The Biggest Loser," which was down nearly 20 percent from last week's premiere.

Some numbers will, of course, change due to the live nature of the football.

On to the numbers...

Among adults 18-49, CBS averaged a 3.2 rating for Thursday night, tops in the key demographic. CBS beat the combined totals for NBC (1.2 key demo), ABC (0.7 key demo), FOX (0.5 key demo) and The CW (0.2 key demo). 

Overall, CBS averaged an estimated 9.02 million viewers and a 5.8 rating/10 share for Thursday, far ahead of the 4.38 million viewers and 3.0/5 for NBC on the night.
