The National Football League as we know it today was formed under another moniker in 1920 for a sport that looked much different from the game we are familiar with today.
More than a century ago, the sport did not include current mainstays like night games and televised broadcasts. Only two current franchises have survived throughout the NFL's entire history—the Chicago Bears and Arizona Cardinals—so there are lots of unfamiliar names in the league's early days. Canton, Ohio, is often recognized today as the home of the Pro Football Hall of Fame; but in the early 1920s, the Canton Bulldogs were one of the NFL's premier clubs.
But not everything was unfamiliar 100 years ago: Names such as George Halas and Red Grange, stars of the NFL's adolescence, still carry an air of reverence.
As the leather helmets and run-heavy trademarks of football gave way to gunslingers and $200 cleats, the NFL underwent a bevy of changes. Teams were spread around the continental U.S. and "Monday Night Football" became a staple of prime time television. Oh, and a little event called the Super Bowl, first played in 1967, has become a de facto national holiday for Americans.
