Fast National ratings for Sunday, April 7, 2013.
 
CBS' broadcast of the 48th Annual Academy of Country Music Awards dominated all three of its hours on Sunday night, building to a crescendo in the 9 p.m. hour and helping the network dominate primetime in all measures.
 
It was the biggest ACM Awards audience in 15 years and the show's top performance in the 18-49 demo since 2001.
 
With the other networks fearing the ACM Awards, or perhaps a slew of high profile cable premieres and finales, Sunday offered little else of note, unless you're excited by a flat week for "Celebrity Apprentice."
 
Among adults 18-49, CBS averaged a 3.6 rating for Sunday night, beating the combined totals for the other three networks in the key demographic. FOX was second with a 1.3 rating, followed by NBC's 1.2 rating and ABC's 0.7 rating in the key demo.
 
Overall, CBS averaged an estimated 13.87 million viewers and an 8.4 rating/14 share for Sunday. NBC was second with a 2.4/4 and 3.735 million viewers, topping ABC's 2.1/3 and 3.27 million viewers. FOX averaged a 1.6/3 and 2.82 million viewers for the night.
 
[Univision averaged 2.42 million viewers and a 0.9 rating among adults 18-49 for Sunday night.]
