Bigger balls were brought in for top events to increase wind resistance and slow the game down because spectotors couldn't follow the fast-paced play. Around 40million Chinese people play table tennis. Since the sport entered the Olympic programme in 1988, China has won 20 of the 24 available gold medals. Top players often smash the ball at speeds exceeding 100 miles per hour. The only European Olympic gold medallist in the sport is Swedish player Jan-Ove Waldner. Nicknamed 'the Mozart of Table Tennis', Waldner won the men's singles at Barcelona in 1992. Barack Obama insisted on a table tennis table being installed in the White House. Aficionados of the sport prefer the tern table tennis. Ping-pong is generally used to discribe recreational play.
