Basketball is a fast, exciting, and entertaining sport played between two teams, each consisting of five players. A team wins games by scoring more points than the opposing team. Players score by shooting a large inflated ball into a raised goal, called a basket, at one end of a basketball court. A player can advance the ball toward the basket only by dribbling (bouncing the ball) or by passing to a teammate. Each team also tries to prevent the other team from scoring.

Basketball was invented in the United States in 1891. By the mid-1900's, it had become the world's most popular indoor sport. Today, millions of fans crowd into gymnasiums and arenas to watch their favorite teams. Millions more watch games on television. In the United States, thousands of elementary schools, high schools, and colleges and universities sponsor amateur teams for male and female players. The finest male players in the world compete as professionals in the National Basketball Association (NBA).

Basketball is a popular form of recreation as well as an organized team sport. Park districts, religious organizations, and youth centers sponsor recreational leagues. Most schools sponsor intramural competition. Both young people and adults enjoy playing on neighborhood playgrounds, in backyards, in alleys, and on driveways. As few as two players can play; all they need is a ball, a basket, and a level surface to serve as the court.

Basketball requires teamwork, quick reactions, and endurance. Tall players have an advantage because they can reach closer to the basket or above other players to shoot and rebound. But smaller players also make contributions to their teams as shooters and ball handlers.
