Gridiron football is a family of team sports derived from rugby football, primarily played in the United States and Canada. It includes American football, Canadian football, and derivative versions such as arena football, flag football, and amateur games like touch and street football.

Lore & Background
The sport developed from informal games played in North America during the 19th century. While a game at University College on the University of Toronto's St. George campus in November 1861 is sometimes cited, its status as the earliest recorded gridiron football game is disputed. The 1874 Harvard-McGill match is generally considered the first recorded game of rugby-style football in North America. In 1874, Harvard and McGill Universities organized two games using each other's rules; Harvard adopted McGill's rugby-style rules, which then spread to Yale and Princeton. American football and Canadian football share a common origin from that 1874 Harvard-McGill contest and influenced each other, though they diverged later.
Reader's Guide
Gridiron football's significance lies in its evolution from rugby into a distinct family of sports that dominate North American athletics. American football, with 11 players, is the best known form worldwide, while Canadian football, with 12 players, predominates in Canada. The sport's international governing body, the IFAF, plays all competitions under American rules but includes Canadian football under its umbrella. Key innovations such as the line of scrimmage, system of downs (devised by Walter Camp), and the forward pass (adopted in 1906) permanently distinguished the game from rugby. The sport is played at professional, collegiate, high school, semi-professional, and amateur levels, with variations like nine-man, eight-man, and six-man football for smaller teams. Despite metrication in Canada, the game retains measurement in customary units of yards.
