James Naismith invented Basketball game in 1891. At that time, basketball was played with a football since ball for basketball didn’t exist. Players used a football which they tossed into a peach basket to score a point. In 1894, Naismith wrote to A. G. Spalding & Bros company asking them to create the first-ever basketball and the first-ever basketball was made of leather, which was dark brown, and it had laces on it. The weight of the ball was approx. 500 gm. and the ball circumference was 32 inches, 4 inches larger than a football. The laces from the ball were evacuated in 1937. There's a data that basketball player and coach, Chuck Taylor was the individual who designed stitch-less ball, which made the ball look and bounce better.
The dark brown colour of the ball wasn’t great since players couldn’t see it well and the audience also couldn’t see the ball at all. Based on Tony Hinkle's (Basketball coach from Butler University) idea, Spalding made an orange ball in 1957, which had its big appearance at NCAA finals in Kentucky in 1958. NCAA was very much impressed with the visibility of the ball, that’s why the orange colour became a standard.
NBA announced Spalding leather ball as the official ball for the game in 1983. The weight & size of the ball is different, depending on the league & whether men, women or juniors are using it. NBA has the rule that circumference of the ball should be 29.5 inches for men, the weight is between 560 and 650gr, whereas women have to play with the ball with a circumference of 29 inches, weight between 510 and 560gr. FIBA incorporates a bit different rules; the ball for men can have circumference from 29.5 inches to 30.7 inches. The air pressure in the ball should be such that when the ball is tossed from a 1.8m height, it should bounce 1.2m to 1.4m. Other than Spalding, balls manufactured by Wilson, Liquid etc. are used.
