The 1920 NFL season was the inaugural regular season of the National Football League. The league was formed at the Jordan and Hupmobile auto showroom in Canton, Ohio on August 20 by four independent professional American football teams from Ohio: Akron Pros, Canton Bulldogs, Cleveland Tigers, and Dayton Triangles. The four parties had played against each other unofficially as the "Ohio League" since 1903, complete with "championships," but it wasn't until 1920 that the league was formalized. At the meeting, they first called their new league the "American Professional Football Conference."
