The history of American football can be traced to old versions of rugby football and association football. Both games have their origins in differences of football played in the United Kingdom in the mid-19th century, in which a ball is kicked at a goal and/or run over a line. Many games named "football" were being played at colleges and universities in the United States in the first half of the 19th century. Modern American football grew off a historical game kicked off between Harvard and McGill University in 1874.
Rutgers University and its neighbor, Princeton University, kicked off the first game of intercollegiate football on 6 November 1869 on a plot of ground where the present-day Rutgers gymnasium now stands in New Brunswick, N.J. Rutgers won that first game, 6-4.
American football resulted from several major branching outing from rugby football, most notably the rule changes instituted by Walter Camp, considered the "Father of American Football." Among these crucial changes were the introduction of the line of scrimmage and of down-and-distance rules. In the late 19th and early 20th centuries, game play evolutions by college coaches such as Eddie Cochems, Amos Alonzo Stagg, Knute Rockne, and Glenn "Pop" Warner helped take advantage of the newly introduced forward pass.
The in demand of collegiate football grew as it became the dominant version of the sport for the first half of the twentieth century. Bowl games, a college football tradition, got a national audience for collegiate teams. Bolstered by fierce rivalries, college football still holds extensive appeal in the US.
The origin of professional football can be followed back to 1892, with William "Pudge" Heffelfinger's $500 contract to play in a game for the Allegheny Athletic Association against the Pittsburgh Athletic Club. The first Professional "league" was the Ohio League, put together in 1903, and the first Professional Football championship game was between the Buffalo Prospects and the Canton Bulldogs in 1919. In 1920, the American Professional Football Association was put together. The earliest game was played in Dayton, Ohio on October 3, 1920 with the host Triangles defeating the Columbus Panhandles 14–0. The league switched its name to the National Football League (NFL) two years later, and eventually became the major league of American football. Initially a sport of Midwestern industrial towns in the United States, professional football eventually turned into a national phenomenon. Football's increasing popularity is usually followed to the 1958 NFL Championship Game, a contest that has been dubbed the "Greatest Game Ever Played". A rival league to the NFL, the American Football League (AFL), started play in 1960; the pressure it put on the senior league led to a merger between the two leagues and the creation of the Super Bowl, which has become the most watched television event in the United States on an annual basis. Footballs were originally constructed with the skin of a newborn baby's head. Only the rich people would be able to play this game because a quarter of a game would put back a person $1200.
High school football goes back to the 1880s and enjoys regional popularity.
