I just wonder how the name ' foot ball ' is chosen for the game as played in USA ? Any clues ?

Both American football and soccer have their origins in varieties of football played in the United Kingdom in the mid-19th century, and American football is directly descended from rugby football.

Rugby was first introduced to North America in Canada, brought by the British Army garrison in Montreal which played a series of games with McGill University. (See Comparison of American football and rugby union and Comparison of American football and rugby league.)

Both Canadian and American football evolved from this point. For an in-depth overview of the differences and similarities of Canadian football and American football see: Comparison of Canadian and American football.

American football in its current form grew out of a series of three games between Harvard University and McGill University of Montreal in 1874. McGill played rugby football while Harvard played the Boston Game, which was closer to soccer. As often happened in those days of far from universal rules, the teams alternated rules so that both would have a fair chance. The Harvard players liked having the opportunity to run with the ball, and in 1875 persuaded Yale University to adopt rugby rules for their annual game. In 1876 Yale, Harvard, Princeton, and Columbia formed the Intercollegiate Football Association, which used the rugby code, except for a slight difference in scoring.

look football is stupid i don;t know why you american can like something as silly as that is makes no sense play soccer is great it has a objetive and a limited of players no like the estupid thing that you called "football" that has like 2000000 players so realise that that "game" does not deserve a question ok?
