Volleyball was invented in 1895 by William G. Morgan in Massachusetts. He created the game of Mintonette as a less rough indoor activity for YMCA members. The game quickly spread to YMCAs across the US and was adapted into volleyball. An international federation was founded in 1947. Beach volleyball became an official Olympic sport in 1996. A volleyball game is played between two teams of six players over a net, with the goal of grounding the ball on the opponent's side without it touching the floor three times. Teams score points by grounding the ball on the other side or causing the opposing team to commit a fault.
