Hugo Award
The Hugo Awards are a set of literary awards given annually for the best science fiction or fantasy works and achievements of the previous year. The awards are named after Hugo Gernsback, the founder of the pioneering science fiction magazine "Amazing Stories", and were officially named the Science Fiction Achievement Awards until 1992. Organized and overseen by the World Science Fiction Society, the awards are given each year at the annual World Science Fiction Convention as the central focus of the event. They were first given in 1953, at the 11th World Science Fiction Convention, and have been awarded every year since 1955. Over the years that the award has been given, the categories presented have changed; currently Hugo Awards are given in more than a dozen categories, and include both written and dramatic works of various types.

Prior to 2017, these could be awarded for the ten years that had a Worldcon where no Hugos were awarded: the conventions in 1939–41, 1946–52, and 1954. Retro Hugos under these rules were given five times: in 1996, 2001, and 2004 for 50 years prior, and 2014 and 2016 for 75 years prior. The Worldcons eligible in 1997–2000, 2002, and 2015 chose not to award Retro Hugos, and under these rules there would have been no more opportunities to award them until 2022 (for 1947).
