The Denver Broncos' 24-10 Super Bowl victory over the Carolina Panthers drew some 111.9 million viewers to make it the third most watched show in US television history.
Viewership tracker Neilsen said preliminary data showed the 50th edition of the NFL's championship extravaganza was viewed in an average of 54.3 million homes.
The huge amount of viewers placed it just behind the 114.4 million who watched Tom Brady and the New England Patriots stun the Seattle Seahawks in last year's Super Bowl and the 112.2 million audience that tuned in during Seattle's blowout win over Denver in the 2014 Super Bowl.
This year's contest in Levi's Stadium, home of the San Francisco 49ers, boasted the compelling storyline of Denver's five-time Most Valuable Player quarterback Peyton Manning possibly playing the last game of his career, against a powerful Panthers team led by rising quarterback star Cam Newton.
However, it did not produce a nailbiting finish to entice more viewers. Nielsen Social found that 16.9 million tweets were sent by 3.8 million individual authors about the Super Bowl 50 telecast on Monday (NZT).
Of that activity on social media site Twitter, 4.6 million tweets were sent by 1.4 million individual authors about the advertisements, while the most-tweeted minute was the one just after the halftime show, when 162,000 tweets were sent.
