This rule still applies for the association football official matches played today all over the world. The early rules specified a weight of 13–15 oz (370–430 g) which was however changed in 1937 to the current accepted weight, 14–16 oz (400–450 g). At the same time, the association agreed that the official association football ball must be covered in leather or any approved material.
A direct consequence of establishing the laws of the game by the English Football Association was the mass production of association football balls. The first two companies that started producing association football balls in larger quantities were Mitre and Thomlinson from Glasgow. They produced balls made of leather because they wanted to produce good quality association football balls that will retain their form after use. On the other hand, they preferred stitching the panels since that means better quality and better and longer resistance in what the ball concerns. The best covers which resulted in very expensive association football balls were the ones made from the rump of a cow. By the 20th century, the official balls were produced with rubber bladders which were able to withstand heavier pressure.[10]
Until the 1950s the official balls used during association football matches had dark colors because of the color of the leather. In 1951 a white ball was first permitted to help spectators see the ball easier with the advent of floodlights. Even if they were used earlier in unofficial games, the official association football balls were permitted only in the mid-20th century.
