<P> Sports that depend primarily on mechanical propulsion, such as motor sports, may not be considered for recognition as Olympic sports, though there were power - boating events in the early days of the Olympics before this rule was enacted by the IOC . Part of the story of the founding of aviation sports' international governing body, the FAI, originated from an IOC meeting in Brussels, Belgium on June 10, 1905 . </P> <P> These criteria are only a threshold for consideration as Olympic sport . In order to be admitted to the Olympic program, the IOC Session has to approve its inclusion . There are many sports that easily make the required numbers but are not recognized as Olympic sports, mainly because the IOC has decided to put a limit on the number of sports, as well as events and athletes, in the Summer Olympics in order not to increase them from the 28 sports, 300 events, and 10,000 athletes of the 2000 Summer Olympics . </P> <P> No such limits exist in the Winter Olympics and the number of events and athletes continue to increase, but no sport has been added since 1998 . The latest winter sport added to the Winter Olympics was curling in 1998 . </P> <P> Previous Olympic Games included sports which are no longer present on the current program, like polo and tug of war . In the early days of the modern Olympics, the organizers were able to decide which sports or disciplines were included on the program, until the IOC took control of the program in 1924 . As a result, a number of sports were on the Olympic program for relatively brief periods before 1924 . These sports, known as discontinued sports, were removed because of lack of interest or absence of an appropriate governing body, or because they became fully professional at the time that the Olympic Games were strictly for amateurs, as in the case of tennis . Several discontinued sports, such as archery and tennis, were later readmitted to the Olympic program (in 1972 and 1984, respectively). Curling, which was an official sport in 1924 and then discontinued, was reinstated as Olympic sport in 1998 . </P>
