Fast National ratings for Tuesday, April 29, 2014.

With "NCIS" routing "The Voice" overall and closing the gap among young viewers to a minuscule 0.2 rating, CBS commandingly won Tuesday in total viewers and was able to eke out a victory in the key demo.

There were mixed returns all around on Tuesday night.

On the positive side, ABC got demo rises for "Marvel's Agents of S.H.I.E.L.D." and "The Goldbergs," "Person of Interest" grew on CBS and NBC saw a bump for "Chicago Fire." The CW also got a good week for the nested "Supernatural" spinoff and also for "The Originals."

On the down side, NBC's "About a Boy" slipped and FOX's "Glee" hit a series low.

And on the neither-good-nor-bad-but-different front, FOX's "The Mindy Project" improved on its "New Girl" lead-in both overall and among young viewers.

On to the numbers.

Among adults 18-49, CBS averaged a 2.2 rating for Tuesday night, nipping the 2.0 rating for NBC in the key demographic. ABC was third with a 1.3 key demo rating, followed by FOX's 1.0 key demo rating. The CW was close behind with a 0.9 key demo rating.
