Football History Around 1050, the English dug up the skull of a Dane and began kicking it as a sign of frustration towards the Dane. It became known as "Kicking the Dane's Head". The skull began to hurt the boy's feet, so one boy had the idea of ​​using an inflated cow bladder to help his feet (Tuttle, 13). In 1189, King Henry banned the game, because people were too involved in the game to practice archery and fight for war (Tuttle, 13). During the 1500s the game moved to Ireland, where the inhabitants invented Irish rules that made the game more difficult. As the game progressed, it transformed into football and rugby (Tuttle, 14). On November 6, 1869, Princeton and Rutgers played the first college football game (Tuttle, 14). During the spring of 1871 a group of people at Harvard University created a game called the “Boston Game,” which was similar to the rules of rugby (Tuttle, 14). On May 15, 1874, Harvard played McGill University, which was from Montreal. They played with an egg-shaped ball instead of a round ball (Tuttle, 14). They played with 11 men instead of 15, because 4 could not participate in the match. In 1880, Yale rugby captain Walter Camp created the line of scrimmage and other attributes of modern football to improve the game because it was too low scoring (Tuttle, 13). He also changed the scoring system to: point safety-1, touchdown-2, point after touchdown-4 and field goal-3. He then changed yards on his knees to get a first down at the 5 and used 3 downs (Tuttle, 16). Later the coaches changed the Camps rules to the ones we use now. In 1919 the American Professional Football Association was founded in Canton, Ohio (Treat, 23). It started with 5 teams (Akron, Canton, Columbus, Dayton and Rochester) (Treat, 23). It cost twenty-five dollars to open a franchise (Treat, 23). The Chicago Bears and Green Bay Packers joined the league in 1921 to create one of football's greatest rivalries. The American Professional Football Association changed its name to the National Football League (NFL) in 1922 (Tuttle, 61). In 1923 there were 20 teams in the NFL (Treat, 34). During the 1920s, largely due to the Depression, the NFL began to decline to just 12 teams (Treat, 35). To increase scoring, the NFL made throwing a forward pass legal in 1933 (Encarta). The defense rushing the quarterback made it difficult to complete passes... middle of paper... ta), where it stopped, but began to pick up again in 1999. In 1992 the National Football League began making major changes toward the future. He created Free Agency, because of a lawsuit (Encarta). Free Agency allows players the freedom to move between teams after their contract. The NFL also invented the Salary Cap, which only allowed NFL teams a certain amount of money to spend on player contracts (Encarta). Both Free Agency and the Salary Cap have made it easier for teams to have the same amount of talent and have made huge strides in the future of football. The demand for football has become so popular that during televised matches, companies will pay millions of dollars for thirty seconds of commercial advertising space. Stadiums now seat tens of thousands of people. At the University of Michigan, the stadium seats more than 100,000 people. Stadiums are now built with retractable roofs and instant replay on every seat. Several indoor football leagues have started across the country, where they play with walls and 50 yards. The owner of the World Wrestling Federation (WWF) is expected to open a tough football league called the XFL in 2001.
