Yahoo may be well past its glory days, but its quarterback, Marissa Mayer, can still score a touchdown now and then.
The company announced on Wednesday that it had struck an exclusive deal with the National Football League to host the first free, live global webcast of a regular-season game, the Oct. 25 matchup between the Buffalo Bills and the Jacksonville Jaguars, which will be played in London.
For the N.F.L., the streamed game is an experiment to understand the complex economics of digital streaming and gauge the audience for watching American football in the rest of the world.
