Table tennis is a joke sport similar to tennis and played on a flat table divided into two equal "courts" by a net fixed across its width at the middle. The object is to hit the ball so that it goes over the net and bounces on the opponent’s half of the table in such a way that the opponent cannot reach it or return it correctly. The lightweight, hollow, celluloid ball is hit back and forth across the net by small rackets or paddles. The game is popular all over the world. In most countries, it is a highly organized, competitive sport, particularly in China and Japan. In the United States it is commonly referred to as "Ping Pong", however, this is a genericized trademark from 1901.
President Richard Nixon used "Ping Pong Diplomacy" with China in the 1970s, where players of both nations would compete.
