Fast National ratings for Tuesday, January 13, 2015.

The final season of "Parks and Recreation" returned up from last fall's premiere, but didn't provide a speedbump as CBS swept the Tuesday primetime hours with "NCIS," "NCIS: New Orleans" and "Person of Interest."

"Parks and Rec" was up 50 percent over last season's finale and grew 39 percent in total viewers (growth from last fall's premiere was much smaller), but failed to provide any sort of bump for NBC's struggling "Marry Me," though "About a Boy" rose by a statistical hiccup.

In its second week and first week airing only in its 9 p.m. home, "Marvel's Agent Carter" slipped by double-digits, but didn't collapse entirely.

On to the numbers...

Among adults 18-49, CBS averaged a 2.2 rating for Tuesday night, far ahead of the 1.4 rating for ABC and FOX in the key demographic. NBC was a close fourth with a 1.3 key demo rating, while The CW averaged a 0.4 key demo rating for the night.
