The history of NFL
The National Football League has a very interesting history. It was created in 1920 and the name was established in 1922 as the NFL. NFL is the largest football league with 32 teams divided into 2 divisions. At first only 11 teams composed NFL and the number increased until today. With American football being the number one sport in the United States, there is no doubt that many of the teams have a big number of fans.
The American football is a very close relative of rugby. The rules differ but the style of play is just about the same. Rugby was very popular in Europe in the 19 century and thus was imported firstly in Canada. From Canada, rugby arrived in the United States where there were some changes operated so the game would be more attractive. The college American football is the point of origin for professional football.
The Eastern part of the United States and in Midwest football raised in popularity so that there was a need for a ruling authority. This ruling authority was founded in 1920 and in 1922 it received the name of National Football League, or the NFL. The first president of this league was Jim Thorpe, a legendary figure for the American football.
After NFL was born the rules of the game became clearer and teams began respecting them. However, there were important teams that pressured for changing the rules so they were changed many times until the final form from the 1970s. It was then when football became the number one sport of the nation and when the sets of rules were crystallized the way we see them today.
Football is not only about the game itself and this is clear especially when you see what Super Bowl means for Americans. Super Bowl is the most important event of the year and many people watch this event.
The TV coverage, the entertainment and other factors create the glamour of every football game. The NFL is the most important sports league in the US and it made decisions for increasing football’s popularity even more. One of these decisions is creating the pre seasonal matches.
In conclusion, NFL had a glamorous history and it should be considered the most important authority in the American sports. It was created 90 years ago and the rules of the football game were crystallized a few decades ago. Football is a very spectacular game in the arena and when watched at TV.
