Fast National ratings for Thursday, January 1, 2015.

The most popular comedy of 2014 was also the most popular show on the first night of 2015, as a repeat of "The Big Bang Theory" was Thursday's top show in all measures, kicking off CBS' comfortable primetime sweep against mostly repeat competition.

The competition wasn't all repeats, of course, though NBC drew no interest for fresh episodes of the already cancelled "Bad Judge" and "A to Z," nor did ABC's "The Taste" find any traction.

"A to Z," in fact, drew only 1.3 million viewers and a 0.4 key demo rating. We'll have to wait to see if another network will declare this the lowest rated in-season rating ever for a network series.

Of course, ESPN's coverage of the Sugar Bowl is likely to have been Thursday's real ratings champion, but those numbers won't be available until later.

On to Thursday's ratings...
