'''Wikia, Inc.''' is a {{tag|Wiki company|company}} registered in the State of Delaware, U.S.A. (corporate number C2935209), whose registered office is at 360 3rd Street, Suite 750, {{tag|San Francisco}}, CA 94107, U.S.A.<ref name="Terms" />
[[Wikia|Wikia.com]] uses a unique and heavily modified creation of the {{tag|MediaWiki}} {{tag|Wiki Engine|wiki engine}}; it is visually different from conventional MediaWiki sites (such as Wikipedia) in that it has its own exclusive {{tag|custom skin}}, and most notably, is embedded with a range and variety of graphic and dynamic {{tag|Advertising|advertisements}}. The fundamental business model of Wikia / Fandom is the offering of {{tag|Free MediaWiki wiki farmfarms|free hosting}} for an individual or community to build a free content [[WhatIsWiki|wiki]]-based website, on virtually any [[:Category:Wiki Topic|subject]]. New wikis can be created instantly at http://www.Wikia.com/Special:CreateNewWiki. Hosting of wiki, and 24 hour customer support is free, in return for advertising placed on the pages; but [[editor]]s and [[user]]s have little say over the advertisements (both content and placement) their wiki site displays. Support, on both the technical and community aspects of running a wiki community, is provided at [[Wikia Community Central]] (or one of its related [[Template:Wikia Community Central|other]] [[:Category:Wiki Language|language]] Community wikis).
[[:Category:Wikia Staff|Wikia staff]] and helpers have [[sysop]] powers throughout <u>all</u> Wikia wikis, as well as several types of automated detection and [[block]]ing tools to help deal with [[vandal]]s and [[spam]] on individual wikis. This can be helpful for [[:Category:Wikis with a strong viewpoint|controversial]] wikis like [[Liberapedia]] which tends to attract vandals.
