Fast National ratings for Monday, March 24, 2014.

"Dancing with the Stars" and "The Voice" were both down week-to-week, but the hoofing and crooning competitions still helped ABC win Monday overall and NBC claim the crown among young viewers.

Monday's biggest notable was a big bump for the penultimate episode of CBS' "How I Met Your Mother," which rippled through in gains for the rest of the network's lineup. 

In contrast, The CW saw a big audience decline for "The Tomorrow People," which fell to "Beauty and the Beast" levels after last week's encouraging time period premiere.

Among adults 18-49, NBC averaged a 3.4 rating for Monday night, comfortably leading the key demographic. ABC was second with a 2.1 key demo rating, nipping CBS' 2.0 key demo rating, while FOX's 1.4 key demo rating and the 0.3 key demo rating for The CW trailed.
