Sunday night saw a dominant performance by the San Antonio Spurs, who dismissed the Miami Heat in five games to win the NBA Championship — and a dominant performance by ABC, which buried its broadcast competition in the ratings.

"Game Five of the NBA Finals generated 17,881,000 viewers, up 10 percent from 16,267,000 viewers last year. Viewership peaked with 22,400,000 viewers in the last half hour. Additionally, Game Five delivered a 10.3 rating, up eight percent from a 9.5 rating last year," ABC announced.

Deadline.com reports: "ABC’s 8-10:52 PM ET broadcast of the game, in which the Spurs won their fifth NBA Championship by extinguishing the Heat 104-87, is the biggest game of this year’s series, and was Sunday’s dominant No. 1 TV program in Total Viewers (17.9 million) and across each of the key adult demographics: A18-34 (6.6 rating), A18-49 (6.8 rating) and A25-54 (7.2 rating), according to fast nationals. Game 5 was up year to year in total viewers (vs. 16.3 million) and 8% in the demo (vs. 6.3 rating). On average, the 2014 NBA Finals grew over the first 5 games of last year’s Spurs-Heat series by 3% in Total Viewers (15.5 million vs. 15.1 million)."

ABC won all five nights of the NBA Finals in total viewership and in the key 18-49 demo, the network noted.

The Deadline report adds: "For the night, ABC more than tripled runner-up CBS in total viewers (212% — 13.4 million vs. 4.3 million) and outscored the other broadcast networks combined in the demo by 143% (5.1/17 vs. 2.1/8 — CBS, NBC and Fox combined). Sunday marked ABC’s most watched non-Oscar Sunday in 3 years."

ABC noted: "On ESPN3, the NBA Finals averaged 374,000 unique viewers, which is up 53 percent from 244,000 unique viewers for the first five games of the 2013 NBA Finals."

The network's announcement adds: "Game Five of the NBA Finals on Twitter was the most-tweeted NBA game of the year with more than 6.4 million tweets, more than triple when compared to Game Five last season. Overall, the 2014 NBA Finals received 16.6 million total tweets, with each game the most-talked about television program of the day on Twitter.
