their chosen guests (so as to avoid having someone chosen by a losing bid feeling that fandom had voted against them personally), so bids do not reveal who their guests are until after the vote, and losing bids generally never reveal who they invited. This is usually treated with the same discretion as the Hugo Awards, where only a few people might know in advance who the guests will be. World Science Fiction Society The name "Worldcon" is owned by the World Science Fiction Society (WSFS), an unincorporated literary society whose purpose is to promote interest in science fiction. WSFS has no standing officers, only small standing committees, and a large membership composed of the members of the current Worldcon. Its main activities are running the selection (voting) process for the annual convention and various awards. The conventions themselves are run by non-profit, volunteer fan organizations, who bid to host the event. The WSFS constitution itself is discussed and amended by the annual general meeting, known as the "business meeting", held at the Worldcon, usually as three morning sessions on successive days. All attending members of the Worldcon may attend, participate, and vote at the Business Meeting, although in practice only a small number of the members actually do so. The WSFS constitution includes rules for site selection, for the Hugo Awards, and for amending itself. The business meeting also empanels a number of ad hoc committees to deal with review of amendments and with certain administrative functions. The only permanent ("standing") committee of WSFS (as opposed to the Business Meeting) is the Mark Protection Committee (MPC), which is responsible for maintaining the society's trademarks and domain names. Site selection Historically, most Worldcons were held in the USA; however, beginning in the later part of the 20th century an increasing number of them have been hosted in other countries. In 2017, the 75th World Science Fiction Convention ("Worldcon 75") was held in Helsinki, Finland; the 2018 Worldcon was held in San Jose, California, and the 2019 Worldcon was held in Dublin. The 2020 Worldcon was scheduled to be in New Zealand; however, due to the COVID-19 pandemic, it was a virtual event (accessed by internet only). The first Worldcon to be held outside the US was the sixth, in 1948 in Toronto, Ontario, Canada, and the first outside North America was the 15th World Science Fiction Convention, in 1957 in
