Fast National ratings for Sunday, April 6, 2014.

Sunday night's telecast of the Academy of Country Music Awards was down significantly from last year, but it still helped CBS cruise to victory in all measures. 

While "Once Upon a Time" was up week-to-week for ABC, the network witnessed continued declines for "Resurrection," plus another drop for "Revenge."

Among new shows, there were also drops for NBC's "Believe" and "American Dream Builders," though both "Cosmos" and "Crisis" were up a hair in total viewers and flat in the key demo.

[Expect "Game of Thrones" premiere numbers either later in the day or tomorrow.]
