Sept 14 (Reuters) - More than 25 ⁠million viewers watched the Seattle Seahawks beat the New ‌England Patriots in the NFL's season opener last week, giving the league a strong prime-time start that eclipsed President Donald Trump's speech ​at a Republican convention.

The Kickoff Game, ⁠a rematch of last ⁠season's Super Bowl LX, averaged more than 25 million viewers ⁠across ‌NBC and Peacock for the fourth straight year, the Comcast-owned network's sports division said on ⁠Monday, citing Nielsen data. .

The game also delivered ​NBC's largest Kickoff ‌Game audience among adults 18 to 49 since ⁠2021, averaging ​10 million viewers in the advertiser-prized demographic across NBC, Peacock and the company's digital platforms, NBC said.

The matchup coincided with ⁠the opening night of the first-ever ​Republican midterm convention, where Trump delivered a speech carried live by Fox News. Trump said the event's "overall numbers beat ⁠the NFL," but did not provide figures or explain his methodology.

Nielsen data showed the speech drew about 2.5 million viewers, potentially undercutting Trump's claim.

The NFL's first regular-season game ​in Australia, meanwhile, drew an ⁠average of 18.5 million U.S. viewers on Netflix, with the ​game between the San Francisco 49ers ‌and Los Angeles Rams peaking ​at 21.3 million.
