‘Dome,’ ‘Dynasty,’ Miley Top TV Last Week

NEW YORK (AP) — With a new season of “Duck Dynasty” and the annual MTV Video Music Awards, two of the three most popular programs on television last week were on cable networks instead of broadcast.

The exception was the CBS miniseries “Under the Dome,” which has led in the ratings for much of the summer.

The MTV awards show was clearly the most talked about program, with Miley Cyrus’ risque dance routine setting social media records. The show was seen live on television Sunday by nearly 10.1 million people, sharply up from the 6.1 million viewers for last year’s program.

The audience was bigger in 2010 and 2011 but slumped in the previous years, according to the Nielsen ratings company. For six years starting in 1999, the audience ranged from 9.8 million to just under 12 million.

In another sign of how the television business has changed, only eight of the 25 most popular shows last week were reruns, including NBC’s weekly recap of the previous week’s “America’s Got Talent.” In years past, there were fewer first-run shows during the dog days of summer.

CBS easily won the week in primetime, averaging 6.1 million viewers. NBC had 4.7 million viewers, ABC had 4.1 million, Univision had 3.2 million, Fox had 2.6 million, Ion Television had 1.2 million, Telemundo had 1.1 million and the CW had 890,000.

USA was the week’s most popular cable network, averaging 2.7 million viewers in prime time. The Disney Channel had 2.4 million, TNT had 2.24 million, ESPN had 2.16 million and History had 2.1 million.

NBC’s “Nightly News” topped the evening newscasts with an average of 7.2 million viewers. ABC’s “World News” was a close second with 7 million, and the “CBS Evening News” had 5.8 million viewers.
