Basketball is a team sport developed in December 1891 by James Naismith, who aimed to create an indoor game that combined elements of football, soccer, and hockey. The game evolved from college play to professional leagues, with the NBA being established in 1949, growing in popularity through key players like Bill Russell, Michael Jordan, and rivalries that defined eras. Fundamental skills include shooting, dribbling, passing, and rebounding, while the game is officiated by referees and umpires to enforce rules and ensure fair play.
