Fast National ratings for Tuesday, March 10, 2015.

Daylight Saving Time sent a slew of of Tuesday offerings plummeting, as "The Voice" helped NBC crush the competition among young viewers and CBS' depressed procedurals eked out a slim victory overall.

In general, TV usage levels -- or HUT levels if you prefer -- were down by 5 percent week-to-week in the 18-49 demo.

Among the shows down either overall, in the key demo or, usually, both on Tuesday were "Fresh Off The Boat," "Marvel's Agents of S.H.I.E.L.D.," "NCIS," "NCIS: New Orleans," "Person of Interest," "The Voice" and "Chicago Fire." And without a new "New Girl" as lead-in, FOX's "The Mindy Project" slipped below The Mulaney Line and also below 2 million viewers on Tuesday.

Let's get to the ugly numbers.

Among adults 18-49, NBC averaged a 3.1 rating for Tuesday night, tops in the key demographic. NBC's total beat the combined 1.7 key demo rating for CBS and 1.2 key demo rating for ABC. FOX was fourth with a 1.0 key demo rating, followed by The CW's 0.3 key demo rating.
