Football, the game of American football as played today by high school, college, and professional teams grew out of rugby-style football which in the mid-1870s replaced a largely kicking game known as association football. Although initially played on village greens and on college fields, the first intercollegiate game took place on 6 November 1869 when Rutgers defeated Princeton 6–4 in a soccer-style game. Five years later, Montreal's McGill University playing at Harvard introduced rugby football, which would be rapidly adopted by eastern teams.
For the first fifty years of football, college teams enjoyed a virtual monopoly of what they called the gridiron the term applied to the football field because of the lines drawn at five-yard intervals. In 1876, students at Harvard, Princeton, Columbia, and Yale met to form the Intercollegiate Football Association, all agreeing to play by rugby rules. Of the four schools, only Yale chose to re-main an independent. Nevertheless, Yale continued to meet with the other schools and played a crucial role in the adoption of new rules and in the popularization of American football. Beginning in the 1880s, the eastern institutions led by Yale played "big games" before large crowds in the New York and Boston areas. From 1880 to 1888, changes in the intercollegiate rules led to the transformation of British rugby into American football. The possession rule of 1880, which decreed that the team with the ball would keep possession if tackled, led to a series of further changes. The result was a game of physical contact and deception that had progressively less in common with rugby and association football.
The possession rule and the changes that accompanied it were associated with Walter Camp, a player for Yale in the late 1870s. A gifted strategist and promoter, Camp served as a coach or adviser to the Yale team from 1879 to 1910 and as the key figure on various rules committees. Through devices such as his All-America teams, he was also instrumental in making football a nationwide intercollegiate sport. Led by Camp, the handful of youthful rules-makers enacted the yards and downs rule three downs to gain five yards, numerical scoring, interference in front of the ball carrier, and tackling between the waist and the knees rather than above the waist. Players could move forward before the snap of the ball momentum plays, and push and pull the ball carrier through the defense mass play. As a result of these rules changes, football became noticeably rougher and by the late 1800s was criticized by clergy, newspaper editors, and some older college faculty and administrators for its dangers and brutality.
