Fast National ratings for Sunday, March 22, 2015.

Boosted by a half-hour of NCAA Tournament overrun, CBS dominated Sunday overall and won a slim victory among young viewers as well.

Due to the live nature of the basketball coverage, Sunday numbers are preliminary, but at least in Fast Nationals, all three of CBS' Sunday dramas slipped overall, though "Madam Secretary" was up in the key demo and the other two were flat.

There was more positive news for FOX's "Last Man on Earth" and ABC's "Secrets & Lies," which both rose a little on Sunday.

FOX also, it should be noted, had sports inflation on Sunday thanks to 30-ish minutes of NASCAR overrun.

On to the numbers...
