Fast National ratings for Tuesday, September 2, 2014.

ABC's hour-long commercial for Disney's "Frozen" couldn't keep up with an "NCIS" repeat as CBS led Tuesday night overall and "America's Got Talent" carried NBC to victory among young viewers.

The "Frozen" special couldn't top CBS' recycled "NCIS" in anything other than the youngest female demos, nor could it compete with last week's special "Bachelor in Paradise" episode, though it did outdraw some of the summer's 8 p.m. airings of "Extreme Weight Loss."

Meanwhile, NBC's "America's Got Talent" was down week-to-week, but "Food Fighters" was basically flat.

On to the numbers...

Among adults 18-49, NBC averaged a 1.5 rating for Tuesday night, topping the 1.3 rating for CBS in the key demographic. ABC's 0.9 key demo rating took third, followed by FOX's 0.6 key demo rating and the 0.2 key demo rating for The CW.
