Demonstration sports were suspended in 1992, as the Olympic program grew bigger and it became more difficult for the organizing committees to give them the appropriate attention, since the IOC required the same treatment to be dispensed for official and demonstration sports.  It is unlikely that they will be reintroduced as a requirement for future Olympic organizing committees. However, the Beijing Olympic Committee has received permission to organize a wushu competition, but it will not be considered a demonstration or exhibition sport at the 2008 Beijing Olympic Games. wikipedia.org
