Dirk Nowitzki #41 of the Dallas Mavericks holds up the Bill Russell Finals MVP trophy after Bill Russell presented it to him following the Mavericks 105-95 win against the Miami Heat in Game Six of the 2011 NBA Finals at American Airlines Arena on June 12, 2011 in Miami.

*ABC was a big winner along with the Dallas Mavericks on Sunday.

Game 6 of the NBA championship series was seen by nearly 24 million people, leading ABC to its most-watched week during the slow summer season in nearly 10 years, according to the Associated Press.

The Nielsen Co. said the Mavericks’ series victory over the Miami Heat was seen by an average of 17.3 million people over the six games. That’s a little less than the viewership for last year’s Lakers-Celtics series, which had the advantage of going to a climactic seventh game.

The fourth, fifth and sixth games of the Heat-Mavericks series eclipsed those corresponding games last year despite the presence of the NBA’s most storied franchises. Many tuned in this year to see if LeBron James would win his first championship after his much-maligned decision to leave the Cleveland Cavaliers.

Take away basketball, and it was a good week for NBC. Two editions of that network’s “America’s Got Talent” and the singing competition “The Voice” did better than any other broadcast network show.

For the week, ABC led with an average of 9.2 million viewers in prime time (5.5 rating, 10 share). CBS had 6.5 million viewers (4.2, 7), NBC had 5.8 million (3.5, 6), Fox had 4.5 million (2.7, 5), ION Television had 1.1 million (0.7, 1) and the CW had 790,000 (0.5, 1).

NBC’s “Nightly News” topped the evening newscasts with an average of 8.2 million viewers (5.4, 11). ABC’s “World News” was second with 7.1 million (4.7, 10) and the “CBS Evening News,” on Scott Pelley’s first week as anchor after Katie Couric’s departure, had 5.7 million viewers (3.8, 8).

  • A ratings point represents 1,147,000 households, or 1 percent of the nation’s estimated 114.7 million TV homes. The share is the percentage of in-use televisions tuned to a given show.
