The name ping-pong was in wide use before English manufacturer J. Jaques & Son Ltd trademarked it in 1901. The name Ping-Pong then came to be used for the game played by the rather expensive Jaques equipment, with other manufacturers calling theirs table tennis.
The turn of the century brought many other refinements to the sport. Players started using celluloid balls after the English man James Gibb discovered them during a trip to the United States in 1901 and proved them to be perfect for Ping-Pong.
