Basketball was invented in 1891 by James Naismith, who nailed two peach baskets to the gym wall and established 13 basic rules. Over time, the rules and regulations of basketball evolved, with the first international rules adopted in 1932 and major changes made in 1998 and 2004. Basketball is played by two teams of five players each, with the objective of throwing the ball into the opponent's 10-foot-high basket. Successful shots are worth 2 or 3 points depending on the distance of the shot.
