Donald Allen Wollheim was an American science fiction editor, publisher, writer, and fan. As an author, he published under his own name as well as under pseudonyms, including David Grinnell, Martin Pearson, and Darrell G. Raynor. A founding member of the Futurians, he was a leading influence on science fiction development and fandom in the 20th-century United States. Ursula K. Le Guin called Wollheim "the tough, reliable editor of Ace Books, in the Late Pulpalignean Era, 1966 and '67", which is when he published her first two novels in Ace Double editions.
A fanzine is a non-professional and non-official publication produced by enthusiasts of a particular cultural phenomenon for the pleasure of others who share their interest. The term was coined in an October 1940 science fiction fanzine by Russ Chauvenet and first popularized within science fiction fandom, and from there the term was adopted by other communities.
A fandom is a subculture composed of fans characterized by a feeling of camaraderie with others who share a common interest. Fans typically are interested in even minor details of the objects of their fandom and spend a significant portion of their time and energy involved with their interest, often as a part of a social network with particular practices, differentiating fandom-affiliated people from those with only a casual interest.
Science fiction is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. It is related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers.
Science fiction fandom or SF fandom is a community or fandom of people interested in science fiction in contact with one another based upon that interest. SF fandom has a life of its own, but not much in the way of formal organization.
Slash fiction is a genre of fan fiction that focuses on romantic or sexual relationships between fictional characters of the same sex. While the term "slash" originally referred only to stories in which male characters are involved in an explicit sexual relationship as a primary plot element, it is now also used to refer to any fan story containing a romantic pairing between same-sex characters. Many fans distinguish slash with female characters as a separate genre, commonly referred to as femslash.
Tolkien fandom is an international, informal community of fans of the works of J. R. R. Tolkien, especially of the Middle-earth legendarium which includes The Hobbit, The Lord of the Rings, and The Silmarillion. The concept of Tolkien fandom as a specific type of fan subculture sprang up in the United States in the 1960s, in the context of the hippie movement, to the dismay of the author, who talked of "my deplorable cultus".
A fan convention is an event in which fans of a particular topic gather to participate and hold programs and other events, and to meet experts, famous personalities, and each other. Some also incorporate commercial activity. The term dates back to at least 1942.
LGBT themes in speculative fiction include lesbian, gay, bisexual, or transgender (LGBT) themes in science fiction, fantasy, horror fiction and related genres.[a] Such elements may include an LGBT character as the protagonist or a major character, or explorations of sexuality or gender that deviate from the heteronormative.
The works of J. R. R. Tolkien have served as the inspiration to painters, musicians, film-makers and writers, to such an extent that he is sometimes seen as the "father" of the entire genre of high fantasy.
Do not laugh! But once upon a time I had a mind to make a body of more or less connected legend, ranging from the large and cosmogonic to the level of romantic fairy-story... The cycles should be linked to a majestic whole, and yet leave scope for other minds and hands, wielding paint and music and drama. Absurd.
A fantasy trope is a specific type of literary trope that occurs in fantasy fiction. Worldbuilding, plot, and characterization have many common conventions, many of them having ultimately originated in myth and folklore. J. R. R. Tolkien's legendarium for example, was inspired from a variety of different sources including Germanic, Finnish, Greek, Celtic and Slavic myths. Literary fantasy works operate using these tropes, while others use them in a revisionist manner, making the tropes over for various reasons such as for comic effect, and to create something fresh.
In subcultural and fictional uses, a mundane is a person who does not belong to a particular group, according to the members of that group; the implication is that such persons, lacking imagination, are concerned solely with the mundane: the quotidian and ordinary. The term first came into use in science fiction fandom to refer, sometimes deprecatingly, to non-fans; this use of the term antedates 1955.
Elements of the supernatural and the fantastic were an element of literature from its beginning. The modern genre is distinguished from tales and folklore which contain fantastic elements, first by the acknowledged fictitious nature of the work, and second by the naming of an author. Works in which the marvels were not necessarily believed, or only half-believed, such as the European romances of chivalry and the tales of the Arabian Nights, slowly evolved into works with such traits. Authors like George MacDonald (1824–1905) created the first explicitly fantastic works.
Fanspeak is the slang or jargon current in science fiction and fantasy fandom, especially those terms in use among readers and writers of science fiction fanzines.

Bob Iger, chief executive of the Walt Disney Company, defined the word franchise as "something that creates value across multiple businesses and across multiple territories over a long period of time".
Fan fiction or fanfiction is fictional writing written in an amateur capacity by fans, unauthorized by, but based on an existing work of fiction. The author uses copyrighted characters, settings, or other intellectual properties from the original creator(s) as a basis for their writing. Fan fiction ranges from a couple of sentences to an entire novel, and fans can retain the creator's characters and settings, add their own, or both. It is a form of fan labor.
