NEW YORK (AP) -- For the fourth time in five years, the Super Bowl has set a record for the most-watched television event in U.S. history, drawing 111.5 million viewers even though the Seattle Seahawks’ 43-8 victory over the Denver Broncos wasn’t really competitive.

The Seattle victory eclipsed the 111.3 million viewers who watched the 2012 Super Bowl between the New York Giants and New England Patriots, according to the Nielsen company. Until last year’s game dipped slightly to 108.7 million, the Super Bowl had set ratings records for the previous three years in a row.

Fox said an average of 528,000 people watched the live Internet stream of the game, peaking at the end of the third quarter. The number of Super Bowl-related tweets was up from 24.1 million last year.

The moment of peak activity on Twitter came after Harvin’s TD jaunt. Harvin’s run produced a 381,605 tweet per minute average, the company said. The next biggest peaks of activity came when Jermaine Kearse caught a touchdown pass and Malcolm Smith returned an interception for a touchdown.

Bruno Mars’ halftime show came in fourth in most heated Twitter activity. In terms of television, though, an estimated 115.3 million watched Mars and his guests, the Red Hot Chili Peppers. That makes it the most-watched Super Bowl halftime show ever, eclipsing Madonna, Fox said.

The three biggest moments on Twitter were also the three most talked-about events on Facebook, that social media company said. Fifty million people accounted for more than 185 million game-related interactions on Facebook.

Fox said that 25.8 million people stuck around after the game to watch the comedy "New Girl" with Prince as guest. The Golden Globe-winning comedy "Brooklyn Nine-Nine," which followed "New Girl," had 14.8 million viewers.
