Changes

'''American football''' was created in the nineteenth century and was derived from Rugby. Originally played at the college level, professional teams were created in 1920.  This version uses a smaller ball than rugby and is the most popular form of football in the U.S. but is rarely played outside that country.  The main difference from rugby is that the game is broken up into a series of plays, each ending when the ball touches the ground, and that for each play the offensive team is allowed one forward pass.  In addition the ball does not need to be grounded to score, but simply carried into the end zone.  The ultimate competition for this sport is the [[National Football League]].
