ABC dominated the broadcast ratings Sunday night, based on Nielsen overnights for the key 18-49 demo. Its formula for success was a simple one: “The 2013 Billboard Music Awards.”

TVbytheNumbers.com reports that the three-hour awards program surged 33% from last year’s telecast, delivering a 3.6 average rating in viewers 18-49. The network opened prime time with the season finale of “America’s Funniest Home Videos,” which rose 29% from a week ago to a 1.8.

Fox, meanwhile, had lackluster results for its season finale of “Family Guy” — a 2.5 average rating in 18-49, down 4% from last year’s finale (but up 8% from last week) — and its season finale of “The Simpsons” — flat with last year with a 2.1. The series finale of “The Cleveland Show” managed a 1.1, ticking up one-tenth from a week ago.

Additional episodes of the Fox series — all of them leading in to the finales — had mixed results: “Cleveland” pulled a 0.9 in adults 18-49, even with last week; “The Simpsons” was down 10% to a 1.8; and “Family Guy” rose 8% to a 2.6. Fox came in second behind ABC for the night.

CBS failed to get much mileage out of its two-hour special “ACM Presents: Tim McGraw’s Superstar Summer Night,” which settled for a 1.2 average rating in the 18-49 demo as CBS finished a distant third in prime time. Back-to-back episodes of “60 Minutes” produced a 1.4 and a 1.3.

NBC’s two-hour season finale of “All-Star Celebrity Apprentice” managed a 1.5 average rating in 18-49, losing a hefty 32% from last year’s season finale but 15% better than last week’s season low for the series. NBC opened prime time with a two-hour repeat of “The Voice,” which mustered only a 0.7 average.

For prime time overall, ABC was comfortably ahead in the 18-49 demo with a 3.1 average, topping Fox (1.8 average), CBS (1.3) and NBC (1.1). ABC also took the win in total viewers with 8.9 million to CBS’s 7.8 million, NBC’s 3.9 million and Fox’s 3.9 million.
