Sunday's Super Bowl broke the record for the biggest US television audience for a single broadcast.
The Green Bay Packers' win over the Pittsburgh Steelers was watched by 111 million viewers, topping the 2010 figures by nearly five million.
Broadcaster Fox said it was also the most-watched night on any network in at least 20 years.
An episode of Glee aired immediately after the American football game drew 26.8 million viewers.
That figure was more than double its usual audience.
"We're excited about the fan reaction from last night and the incredible game they were able to see," National Football League (NFL) commissioner Roger Goodell said.
Last year, 106.5 million viewers saw the New Orleans Saints beat the Indianapolis Colts, beating the 28-year record held by the finale of the comedy MASH in 1983.
Christina Aguilera fluffed a line of the Star-Spangled Banner as she belted out a version of the US national anthem to open Sunday's Super Bowl in Texas.
The singer should have sung: "O'er the ramparts we watched, were so gallantly streaming?" but repeated an earlier line with a slight variation.
Aguilera, 30, said afterwards she had got lost in the moment.
The anthem is one of the set piece events of the glittering Super Bowl pre-game ceremony.
