National Football League

On September 17, 1920, representatives from four Ohio athletic clubs gathered in Ralph Hay’s Hupmobile showroom in Canton and agreed to form the American Professional Football Association. The franchise fee was $100—a sum most owners never actually paid. The league’s early years were chaotic: teams appeared and vanished between seasons, schedules were informal, and the champion was often determined by a vote rather than a playoff.

Yet even in this primordial era, the seeds of greatness were planted. Jim Thorpe, the Olympian and Carlisle Indian School legend, lent his celebrity to the fledgling circuit. Red Grange’s barnstorming tour with the Chicago Bears in 1925 proved that professional football could fill stadiums and capture headlines. The league rebranded as the National Football League in 1922, and by the end of the decade, franchises in New York, Chicago, and Green Bay had established the geographic spine that would endure for a century.

The NFL’s transformation from a loosely organized barnstorming circuit into a recognizable professional sports league began in 1933, when the competition split into two divisions and staged its first official championship game. The Chicago Bears defeated the New York Giants 23–21 at Wrigley Field in a contest that established the template for everything that followed: a single, decisive game to crown a champion.

The rules were reshaped to favor the forward pass, opening up the game and creating the aerial spectacle that would eventually define the sport. Sammy Baugh of Washington threw the ball with an accuracy previously unimagined, and the T-formation, popularized by Bears coach George Halas, rendered the old single-wing offense obsolete. World War II depleted rosters—the Steelers and Eagles temporarily merged into the “Steagles”—but the league survived, and the postwar years brought a golden generation of talent headlined by Otto Graham’s Cleveland Browns.

The 1958 NFL Championship—the Baltimore Colts’ overtime victory over the New York Giants at Yankee Stadium—is remembered as “The Greatest Game Ever Played,” not because of its quality alone but because forty-five million Americans watched it on television. In a single afternoon, professional football announced itself as a medium perfectly suited to the screen: dramatic, violent, and punctuated by natural pauses ideal for commercial breaks.

The American Football League, founded in 1960 by owners the NFL had rebuffed, forced a bidding war for talent that drove up salaries and expanded the game’s reach into new markets—Houston, Denver, Oakland, Kansas City. The rivalry between the two leagues culminated in the first AFL–NFL World Championship Game in January 1967, retroactively named the Super Bowl. Vince Lombardi’s Green Bay Packers won the first two, but Joe Namath’s guarantee and the Jets’ upset in Super Bowl III proved the AFL could compete—and made the merger inevitable.

The AFL–NFL merger, completed in 1970, created the modern conference structure—the AFC and NFC—and established the Super Bowl as the de facto national championship. Commissioner Pete Rozelle’s masterstroke was the television revenue-sharing model: every team, regardless of market size, received an equal share of the broadcast money, giving Green Bay the same financial footing as New York.

The Pittsburgh Steelers, coached by Chuck Noll and anchored by the Steel Curtain defense, won four Super Bowls in six years and became the decade’s defining dynasty. The Dallas Cowboys, with their computerized scouting and corporate polish, earned the “America’s Team” label. Monday Night Football, launched in 1970 with Howard Cosell’s unmistakable voice, turned the sport into prime-time entertainment and cemented the NFL’s cultural dominance.

The 1980s brought seismic off-field changes. The USFL’s brief existence challenged the NFL’s monopoly and produced stars like Herschel Walker, Steve Young, and Jim Kelly who would reshape rosters for years. Meanwhile, franchise relocations—the Colts’ midnight move from Baltimore to Indianapolis, the Raiders’ sojourn in Los Angeles—revealed the leverage owners held over their host cities.

On the field, the San Francisco 49ers and their West Coast Offense, engineered by Bill Walsh and executed by Joe Montana, redefined what a passing attack could look like. Their four championships in nine years set a standard of sustained excellence. But the decade’s most consequential moment may have been the introduction of free agency in 1993, which, paired with the salary cap, created the modern economic framework that would make parity the league’s defining characteristic.

The salary cap was supposed to end dynasties. For a while, it seemed to work: the mid-1990s saw a parade of different champions, from the Cowboys’ Triplets-era hat trick to the Broncos’ back-to-back titles with John Elway. Then Tom Brady and Bill Belichick’s New England Patriots arrived and spent two decades proving that a great quarterback and a great coach could sustain excellence under any economic regime.

The Patriots won three of four Super Bowls between 2002 and 2005, lost the 2008 championship to the Giants in one of the greatest upsets in sports history, and then reassembled to win again. Their sustained dominance—and the league’s inability to prevent it through rules alone—became the central narrative of the era. Meanwhile, the NFL expanded to 32 teams, moved the Super Bowl into rotation among purpose-built venues, and signed television contracts that made it the most valuable property in American media.
