The first ever intercollegiate football game between two American teams played under rules which would eventually become the rules under which modern American football is governed occurred between Princeton and Rutgers University in 1869. However, this game was far more like that of soccer than what has come to be recognized as American football. The completion of the first ever American football season came as a result of only two total games being played. Yale, together with Rutgers, Princeton and Columbia met on October 20, 1873 at the Fifth Avenue Hotel in New York City to agree a set of rules and regulations that would allow them to play a form of football that was essentially Association football (today often called "soccer" in the US) in character. Harvard University turned down an invitation to join this group because they preferred to play a rougher version of football called "the Boston Game" in which the kicking of a round ball was the most prominent feature though a player could run with the ball, pass it, or dribble it (known as “babying”). The man with the ball could be tackled, although hitting, tripping, “hacking” (shin-kicking) and other unnecessary roughness was prohibited. There was no limit to the number of players, but there were typically ten to fifteen per side. Walter Camp, known as the "Father of American Football", is credited with changing the game from a variation of rugby into a unique sport. Camp, who was a rugby coach, decided to come up with a new set of rules to create a game that was completely different. Camp is responsible for pioneering the play from scrimmage with initially uncontested possession for the team starting with the ball (earlier games featured a rugby scrum where possession was contested) and was also the one who decided that teams should have 4 downs to advance the ball ten yards. Camp was responsible for the eleven-man team. Camp also had a hand in popularizing the game. He published numerous articles in publications such as Collier's Weekly and Harper's Weekly, and he chose the first College Football All-America Team. College football increased in popularity through the remainder of the 19th century. It also became increasingly violent. Between 1890 and 1905, 330 college athletes died as a direct result of injuries sustained on the football field. These deaths could be attributed to the mass formations and gang tackling that characterized the sport in its early years. In 1906, President Theodore Roosevelt organized a meeting among thirteen school leaders at the White House to find solutions to make the sport safer for the athletes. Because the college officials could not agree upon a change in rules, it was decided over the course of several subsequent meetings that an external governing body should be responsible. Resulting from this conference was the formation of the Intercollegiate Athletic Association of the United States in 1906. The IAAUS was the original rule making body of college football, but would go on to sponsor championships in other sports. The IAAUS would get its current name of National Collegiate Athletic Association (NCAA), in 1910 which still sets rules governing the sport
