Basketball at the Summer Olympics was invented by James Naismith in Springfield, Massachusetts, in 1891. Within a few decades, the new game became popular throughout the United States as an indoor sport. The popularity spread overseas and the International Basketball Federation (FIBA) was organized in 1932 in Geneva, Switzerland. Thanks in part to the effort of Phog Allen—a Kansas Jayhawks collegiate coach—the first Olympic basketball tournament was organized in the 1936 Berlin Olympics on outdoor tennis courts. Dr. Naismith presented the medals to the top three teams. According to the Olympic rules of that time, all of the competitors were amateurs. The tournament was held
James Naismith could help its track athletes to keep in shape and explicitly emphasized to "make it fair for all players and not too rough." In his attempt to think up a new game, Naismith was guided by three main thoughts. Firstly, he analyzed the most popular games of those times (rugby, lacrosse, soccer, football, hockey, and baseball); Naismith noticed the hazards of a ball and concluded that the big soft soccer ball was safest. Secondly, he saw that most physical contact occurred while running with the ball, dribbling or hitting it, so he decided that passing was the only legal option.
