Sunday’s Golden State-Houston game on ABC matched the best overnight rating for any first-round NBA Playoff game on any network in the past 12 years.

The Warriors’ win in Game 4 was up 6% from last year’s comparable first-round game on ABC – Los Angeles Clippers vs. San Antonio Spurs – which posted a 5.0 overnight rating. That 5.3 overnight rating matches Miami Heat vs. New York Knicks on ABC, back on May 6, 2012, and Chicago Bulls vs. Boston Celtics on TNT, going back to May 2, 2009, as the best in 12 years.

In San Francisco, Game 4 delivered a 20.7 rating – the highest-rated first-round NBA playoff game in the market across any network as far as records go back (2003). In Houston, the game drew a 10.9 rating – the second-highest-rated first-round game in the market ever.

Broadcast networks prefaced this morning’s primetime ratings reports with reminders of Game of Thrones clubbing as the HBO drama returned at 9 PM for Season 6. ABC took the broadcast lead in Sunday night primetime among adults 18-49 (1.0/3), while CBS scored a commanding lead in overall audience (8.2M viewers). ABC’s America’s Funniest Home Videos and Once Upon a Time tied Fox’s The Simpsons as Sunday’s No. 1 broadcast series in the demo. CBS’ newsmag 60 Minutes was the most-watched broadcast primetime program (9.8M).

60 Minutes and AFHV split control of 7 PM. Once (1.2, 3.8M) and CBS’ Madam Secretary (1.0, 9.5M) did the honors at 8 PM. CBS’s The Good Wife controlled 9 PM in both metrics (1.0, 8.4M). Quantico (1.0, 3.4M) took back the demo lead for ABC at 10, while CBS’ Elementary hung on to total viewers (0.7, 5.2M).
