The return of the National Football League, with two gripping prime-time games, sent NBC vaulting into the week's lead in Nielsen's television ratings.
With the other networks' fall premieres still a couple of weeks away, it was no contest.
Sunday's thrilling comeback win by the New York Jets over the Dallas Cowboys was seen by 25.8 million people, the Nielsen ratings company said. It was the most-watched Sunday night game since NBC began that franchise in 2006 and was the most-watched Sunday or Monday night game in 14 years.
But it wasn't even the most-watched game of the week. Thursday's season kickoff between the New Orleans Saints and the Super Bowl champion Green Bay Packers had more than 27 million viewers, Nielsen said.
The six most popular prime-time programs last week were football games, football pregame shows or football highlights shows.
CBS News' update of its Sept. 11 documentary, shot by two French-born American filmmakers who caught a view of the first plane crashing into the World Trade Center, had 12.3 million viewers. That was second only to one night of "America's Got Talent" as the most popular non-football show. Another 9/11-related show, the "Dateline NBC" special with Tom Brokaw, also finished among Nielsen's top 20.
Last week's finale of "Pequenos Gigantes" ("Little Giants") on Univision was seen by 6.2 million people, the most ever for a Spanish-language reality show. The three-hour show was ranked No. 21 among all programs on TV last week.
NBC averaged 11 million viewers in prime-time (6.7 rating, 11 share). CBS was second with a 6.3 million viewer average (4.1, 7), ABC had 4.8 million (3.1, 5), Fox had 4.3 million (2.6, 4), ION Television had 1.2 million (0.8, 1) and the CW had 870,000 (0.6, 1).
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.
Among the Spanish-language networks, Univision led with a prime-time average of 3.9 million viewers (2.1, 3), Telemundo had 870,000 (0.5, 1), TeleFutura had 490,000 (0.3, 0), Estrella had 190,000 (0.1, 0) and Azteca had 180,000 (also 0.1, 0).
NBC's "Nightly News" topped the evening newscasts with an average of 8.6 million viewers (5.6, 11). ABC's "World News" was second with 7.5 million (5.1, 10), and the "CBS Evening News" had 5.9 million viewers (3.9, 8).
