About
The World Science Fiction Convention (Worldcon) is an annual international gathering of science fiction and fantasy fans, writers, artists, musicians, and creators. First held in New York City in 1939, Worldcon visits a new city around the globe each year and is organized by a different group of dedicated volunteers who participate in a bidding process that is open to any group that meets a small number of technical regulations.
