People always wonder “what’s the difference between table tennis and ping pong?”
Some people think the basic difference is in playing technique, type of equipment, even the scoring and number of the bounces the ball makes.
Some defining table tennis as “sport” and ping pong as a “game”.
The right answer is this: They are the same, there is no difference between table tennis and ping pong
Where does the confusion come from ? In order to understand you have look at history.
Wikipedia has a good section on the history, so let not rewrite that:
The sport originated in Victorian England, where it was played among the upper-class as an after-dinner parlour game It had several different names, including ‘whiff-whaff’, and it has been suggested that makeshift versions of the game were developed by British military officers in India or South Africa, who brought it back with them.
A row of books was stood up along the center of the table as a net, two more books served as rackets and were used to continuously hit a golf-ball. The name “ping-pong” was in wide use before British 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’s equipment, with other manufacturers calling it table tennis. A similar situation arose in the United States, where Jaques sold the rights to the “ping-pong” name to Parker Brothers. Parker Brothers then enforced their trademark for the term in the 1920s making the various associations change their names to “table tennis” instead of the more common, but trademarked, term.
