Fast National ratings for Tuesday, March 11, 2014.

Even with three procedural repeats, CBS was the most watched network on Tuesday night, while NBC's "The Voice" was the night's top show among young viewers and led a primetime sweep.

With "The Voice" down week-to-week, both "About a Boy" and "Growing Up Fisher" also posted drops -- Somewhat sizable for "Boy" and a bit more modest for "Fisher." However, with "Person of Interest" airing a repeat, "Chicago Fire" got to be up week-to-week.

Percentage-wise, the night's biggest gainer was actually "Mind Games" on ABC, which rose from a dismal 0.6 key demo rating to a dismal 0.9 key demo rating with "PoI" out. ABC's lineup had mixed returns, as "Marvel's Agents of S.H.I.E.L.D." was up, but "The Goldbergs" dropped a little.

Finally, "Glee" dropped to a 0.9 in the key demo rating, which tied with The CW's "Originals" for that hour.
