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]].

The most popular of these football games is '''Soccer'', played professionally as '''Association Football''' and generally known as "football" outside the U.S. It is played on a field where possession of a round ball is competed for by two teams of eleven people who (with the exception of the goalkeepers) may not touch the ball with their hands or arms. The aim of the game is to score goals by propelling the ball into the goal of the opposing team. The governing body is [[FIFA]], the International Federation of Football Asociations. The name Soccer, a derivation from "Association" Football, is most commonly used in countries such as the [[U.S.]] and [[Australia]] where other forms of football are more popular. This version of the game was derived in [[Great Britain]] and was the first to be professionalized.  It is particularly popular in Europe, South America, Asia and Africa. Professional leagues exist in many countries, most notably in [[England]], [[Italy]] and [[Spain]].  The ultimate competition for this sport is the [[FIFA World Cup]] held every four years.
