Following is a list of multimedia franchises originating in television series, whether animated or live-action.
In the following tables, the initial media through which the franchise characters or settings became known is shown in boldface. Only works of fiction are considered part of the series; a book or a documentary film about the franchise is not itself an installment in the franchise.
Fictional languages are the subset of constructed languages (conlangs) that have been created as part of a fictional setting. Typically they are the creation of one individual, while natural languages evolve out of a particular culture or people group, and other conlangs may have group involvement. Fictional languages are also distinct from natural languages in that they have no native speakers. By contrast, the constructed language of Esperanto now has native speakers.
The Romulans are an extraterrestrial race in the American science fiction franchise Star Trek. They first appeared in the series Star Trek (1966–1969). They have appeared in most subsequent Star Trek releases, including The Animated Series, The Next Generation, Deep Space Nine, Voyager, Enterprise, Discovery, Picard, Strange New Worlds, and Lower Decks. They appear in the Star Trek feature films Star Trek V: The Final Frontier (1989), Star Trek VI: The Undiscovered Country (1991), Star Trek: Nemesis (2002) and Star Trek (2009). They also appear in various other spin-off media, including books, comics, toys and games.
Michael Dorn is an American actor best known for his role as the Klingon character Worf in the Star Trek franchise, appearing in all seven seasons of the television series Star Trek: The Next Generation (1987–1994), and later reprising the role in Seasons 4 through 7 of Star Trek: Deep Space Nine (1995–1999) and season three of Star Trek: Picard (2023). Dorn has appeared more times as a regular cast member than any other Star Trek actor in the franchise's history, spanning five films and 284 television episodes.
The canon of a work of fiction is "the body of works taking place in a particular fictional world that are widely considered to be official or authoritative; [especially] those created by the original author or developer of the world". Canon is contrasted with, or used as the basis for, works of fan fiction and other derivative works.
The term expanded universe, sometimes called an extended universe, is generally used to denote the "extension" of a media franchise with other media, generally comics and original novels. This typically involves new stories for existing characters already developed within the franchise, but in some cases entirely new characters and complex mythology are developed. This is not necessarily the same as an adaptation, which is a retelling of the same story that may or may not adhere to the accepted canon. It is contrasted with a sequel that merely continues the previous narrative in a linear sequence. Nearly every media franchise with a committed fan base has some form of expanded universe.
A media franchise, also known as a multimedia franchise, is a collection of related media in which several derivative works have been produced from an original creative work of fiction, such as a film, a work of literature, a television program or a video game. 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".
In 1966, Bantam Books acquired the license to publish tie-in fiction based on the science fiction television series Star Trek.
Star Trek is an American science fiction media franchise created by Gene Roddenberry, which began with the eponymous 1960s television series and became a worldwide pop-culture phenomenon. Since its creation, the franchise has expanded into various films, television series, video games, novels, and comic books, and it has become one of the most recognizable and highest-grossing media franchises of all time.
Voyages of Imagination: The Star Trek Fiction Companion (2006) is a reference work by Jeff Ayers published by Pocket Books. The book contains entries on the production and publication of Star Trek tie-in novels published from 1967 to 2006. Included are brief synopses of plots for each featured novel.
A shared universe or shared world is a fictional universe from a set of creative works where one or more writers independently contribute works that can stand alone but fits into the joint development of the storyline, characters, or world of the overall project. It is common in genres like science fiction. It differs from collaborative writing in which multiple artists are working together on the same work and from crossovers where the works and characters are independent except for a single meeting.
Star Wars has been expanded to media other than the original films. This spin-off material is licensed and moderated by Lucasfilm, though during his involvement with the franchise Star Wars creator George Lucas reserved the right to both draw from and contradict it in his own works. Such derivative works have been produced concurrently with, between, and after the original, prequel, and sequel trilogies, as well as the spin-off films and television series. Commonly explored Star Wars media include books, comic books, and video games, though other forms such as audio dramas have also been produced.
The following outline is provided as an overview of and topical guide to Star Trek:
A multimedia franchise is a media franchise for which installments exist in multiple forms of media, such as books, comics, films, television series, animated series and video games. Multimedia franchises usually develop due to the popularization of an original creative work, and then its expansion to other media through licensing agreements, with respect to intellectual property in the franchise's characters and settings, although the trend later developed wherein franchises would be launched in multiple forms of media simultaneously.
