Worldcon

The World Science Fiction Convention is the principal annual gathering of science fiction fandom -- fandom's family reunion. Officially sponsored by the the World Science Fiction Society, it is actually run by a different organization each year which has bid to run it and been selected by vote of the membership (see Site Selection. It also bestows the Hugo Awards.

The Worldcon has been held each year since 1939 (except during 1942–1945 World War II), and moves to a different city each year. It is the oldest convention with a continuing existence. While most of the conventions occur in the United States, the event has also been hosted by Australia, Canada, Germany, Japan, Great Britain, Finland, Ireland, and the Netherlands. And it will soon be hosted by New Zealand.

It is an entirely volunteer-run effort.

The one, the only, annual world science fiction convention at which the Hugos are given out. As a service mark "Worldcon" should always be capitalized. Technically it may not be necessary for Worldcons held before it was made a service mark, but why split hairs?

From Fancyclopedia 2, ca. 1959

The chief annual gathering of fans is usually designated as an "International Convention." See Convention.
