In 1903, I saw a photograph of a professional basketball court. It measured 65 feet by 35 feet and had no markings other than a central circle. But what was truly bizarre was the massive wire cage that surrounded the court and hung from the 11-foot-high ceiling. The cage was made of metal bars spaced about two feet apart. At each end were two rings through which the rope that held up the netting was attached. This camera caught some famous people in 1903: John D. Rockefeller, Theodore Roosevelt, Albert Einstein, and Charlie Chaplin among others. Basketball was first played in 1891 but did not become popular until after World War II when it became a national pastime. In 1972, the NBA started using the 3-point line instead of the 2-point line to make the game more exciting to watch. Today, many stadiums around the world have basketball courts for athletes to use as training grounds before big games. Now, if you'll excuse me, I'm going to go shoot some hoops!
