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 organised 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.
The longest running Science Fiction convention in the world, Worldcon originally focused on only Science Fiction and Fantasy. While both remain important, Worldcon continues to grow with each year of its celebration; now including genre television, films, animation, role-playing and table-top gaming, video games and other popular media as well. Since the mid-1970s, Worldcons have had an average attendance of 4,000-5,000 fans, with more or less depending on the host city.
