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.
Wiktionary is a multilingual, web-based project to create a free content dictionary of terms in all natural languages and in a number of artificial languages. These entries may contain definitions, images for illustration, pronunciations, etymologies, inflections, usage examples, quotations, related terms, and translations of terms into other languages, among other features. It is collaboratively edited via a wiki. Its name is a portmanteau of the words wiki and dictionary. It is available in 195 languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation, and is written collaboratively by volunteers, dubbed "Wiktionarians". Its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries.
MediaWiki is free and open-source wiki software originally developed by Magnus Manske for use on Wikipedia on January 25, 2002, and further improved by Lee Daniel Crocker, after which development has been coordinated by the Wikimedia Foundation. It powers several wiki hosting websites across the Internet, as well as most websites hosted by the Wikimedia Foundation including Wikipedia, Wiktionary, Wikimedia Commons, Wikiquote, Meta-Wiki and Wikidata, which define a large part of the set requirements for the software. Besides its usage on Wikimedia sites, MediaWiki has been used as a knowledge management and content management system on websites such as Fandom, wikiHow and major internal installations like Intellipedia and Diplopedia.
The English Wikipedia is the primary English-language edition of Wikipedia, an online encyclopedia. It was created by Jimmy Wales and Larry Sanger on 15 January 2001, as Wikipedia's first edition.

It has been owned by Fandom, Inc. since October 2022.

LyricWiki was an online wiki-based lyrics database and encyclopedia. In March 2013, it was the seventh largest MediaWiki installation with over 2,000,000 pages including 1.5 million songs. Prior to its shutdown, users on the site could view, edit, and discuss the lyrics of songs, which were also available for purchase from links on the site. Users were told to be mindful of copyright while contributing, and copyright violations were removed upon request. All the lyrics on LyricWiki were licensed through LyricFind.
Conservapedia is an English-language, wiki-based, online encyclopedia written from a self-described American conservative and fundamentalist Christian point of view. The website was established in 2006 by American homeschool teacher and attorney Andrew Schlafly, son of the conservative activist Phyllis Schlafly, to counter what he perceived as a liberal bias on Wikipedia. It uses editorials and a wiki-based system for content generation.
Wikivoyage is a free web-based travel guide for travel destinations and travel topics written by volunteer authors. It is a sister project of Wikipedia and supported and hosted by the same non-profit Wikimedia Foundation (WMF). Wikivoyage has been called the "Wikipedia of travel guides".
Uncyclopedia is the name of several forks of satirical online encyclopedias that parody Wikipedia. Its logo, a hollow "puzzle potato", parodies Wikipedia's globe puzzle logo, and it styles itself as "the content-free encyclopedia", parodying Wikipedia's slogan of "the free encyclopedia" and likely as a play on the fact that Wikipedia is described as a "free-content" encyclopedia. Founded in 2005 as an English-language wiki, the project spans more than 75 languages as well as several subprojects parodying other wikis. Uncyclopedia's name is a portmanteau of the prefix un- and the word encyclopedia.
The Wikimedia Foundation, Inc., abbreviated WMF, is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California, and registered there as a charitable foundation. It is the host of Wikipedia, the seventh most visited website in the world. It also hosts fourteen related open collaboration projects, and supports the development of MediaWiki, the wiki software which underpins them all. The foundation was established in 2003 in St. Petersburg, Florida by Jimmy Wales, as a non-profit way to fund Wikipedia and other wiki projects which had previously been hosted by Bomis, Wales' for-profit company.
The Organization for Transformative Works (OTW) is a nonprofit, fan activist organization. Its mission is to serve fans by preserving and encouraging transformative fan activity, known as "fanwork", and by making fanwork widely accessible.
Fandom is a wiki hosting service that hosts wikis mainly on entertainment topics. The privately held, for-profit Delaware company was founded in October 2004 by Wikipedia co-founder Jimmy Wales and Angela Beesley. Fandom was acquired in 2018 by TPG Inc. and Jon Miller through Integrated Media Co.
Warcraft Wiki is a fan wiki about the Warcraft fictional universe. It covers all of the Warcraft games, including the MMORPG World of Warcraft.

It was officially announced on 25 October 2010.
