Volleyball was created in 1895 by William G. Morgan in Massachusetts. It became an Olympic sport in 1964. The game is played by two teams on a divided court, with a net in between. Teams can comprise up to 6 players and must win three sets, with each set consisting of gaining 25 points with a two point advantage. Key differences between indoor and beach volleyball include the playing surface, team size, scoring system, and rules around blocks and coaching.
