what type of basketball is used in the nba
Basketball (ball) Spalding was the first company to produce a basketball for official use. Company founder A.G. Spalding made the first dedicated basketball in the last years of the 19th century at the behest of James Naismith. It has produced basketballs since that time and has produced the NBAâ€™s official game ball since 1983. They also produce the balls for the Women's National Basketball Association and NBA Development League. The company also produces a wide variety of balls for the consumer market.
Rules of basketball The center jump ball that was used to restart a game after every successful field goal was eliminated in 1938, in favor of the ball being given to the non-scoring team from behind the end line where the goal was scored, in order to make play more continuous. The jump ball was still used to start the game and every period, and to restart the game after a held ball. However, the NBA stopped using the jump ball to start the second through fourth quarters in 1975, instead using a quarter-possession system where the loser of the jump ball takes the ball from the other end to start the second and third periods, while the winner of that jump ball takes the ball to start the fourth period from the other end of the court.
