The winter Olympics were begun in 1924 and were held in the same year as the summer games until the 1994 winter games in Lillehammer, Norway, when the alternating cycles began.
The 1992 Olympics in Barcelona, Spain, reflected a changed political landscape: the 172 participating nations and territories included the Unified Team (with athletes from 12 former Soviet republics), a reunited Germany, and South Africa, which was allowed to compete for the first time since 1960.
The Olympic games are competitions of individual athletes, not of nations, and the IOC does not keep national scores; however, the media of all nations report national standings according to one of two scoring systems.
The 1900 SummerOlympics, officially known as the Games of the II Olympiad, were held in 1900 in Paris, France.
Swimming and water polo are considered to be two disciplines within the single sport called aquatics in the Olympic context.
Gold, silver, and bronze medals were retroactively awarded by the International Olympic Committee to reflect later practice of awarding such medals to 1st, 2nd, and 3rd place competitors, respectively.
