Basketball rapidly spread throughout the United States and beyond, thanks to the YMCA network and Naismith's efforts to promote the game.

College basketball emerged as a major spectator sport, with teams competing regionally and nationally. The rules of the game were refined and standardized.

Basketball made its official debut as an Olympic sport at the 1936 Summer Olympics in Berlin, marking a significant milestone in the game's global recognition.

Professional basketball leagues, such as the NBA, were established, and the game continued to grow in popularity around the world. Basketball became a truly global sport, played and enjoyed by millions of people.

Basketball remains one of the most popular sports in the world, a testament to James Naismith's innovative spirit and his vision for a game that promotes skill, teamwork, and sportsmanship.
