Hugo Award for Best Series
The Hugo Awards are given every year by the World Science Fiction Society for the best science fiction or fantasy works and achievements of the previous year. The award is named after Hugo Gernsback, the founder of the pioneering science fiction magazine "Amazing Stories", and was once officially known as the Science Fiction Achievement Award. It has been described as "a fine showcase for speculative fiction" and "the best known literary award for science fiction writing". The Hugo Award for Best Series is given each year for series of science fiction or fantasy stories published consisting of at least 3 works totaling at least 240,000 words, with at least one work released or translated into English during the previous calendar year. The Hugo Award for Best Series has been awarded annually since 2017. It was started then as a one-time special Hugo Award in advance of a vote to make it a permanent category, and was ratified as such by members of the World Science Fiction Society that year.
Hugo Award for Best Dramatic Presentation
Beginning with the 1996 Worldcon, the World Science Fiction Society created the concept of "Retro Hugos", in which the Hugo award could be retroactively awarded for 50, 75, or 100 years prior. Retro Hugos may only be awarded for years in which a Worldcon was hosted, but no awards were originally given. Retro Hugos have been awarded six times, 50 years later for the years 1946, 1951, and 1954, and then 75 years later for the years 1939, 1941, and 1943. In 1946 and 1951, an award was given for Best Dramatic Presentation, as the category had not yet been split, while in 1939, 1943, and 1954 an award was given for Best Dramatic Presentation, Short Form. The Long Form category did not receive enough nominations for an award to be given in those years. The 1941 Retro Hugos awarded both Long and Short Forms. In 2018, the Retro Hugo for Best Dramatic Presentation (Short Form) will be awarded for 1943.
