A football, or association football ball is the ball used in the sport of association football. The name of the ball varies according to whether the sport is called "football", "soccer", or "association football". The ball's spherical shape, as well as its size, weight, and material composition, are specified by Law 2 of the Laws of the Game maintained by the International Football Association Board. Additional, more stringent, standards are specified by FIFA and subordinate governing bodies for the balls used in the competitions they sanction.
Early footballs began as animal bladders or stomachs that would easily fall apart if kicked too much. As time went on, footballs developed into what they look like today. This was possible with the help of people like Charles Goodyear and Domenico Nobili, who introduced rubber and their discoveries of vulcanisation to the design of footballs. Today, technological research is ongoing to develop footballs with improved performance.
