Wikimedia Foundation

The Wikimedia Foundation, Inc. (WMF) is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California, and registered as a charitable foundation under local laws. Best known as the hosting platform for Wikipedia, a crowdsourced online encyclopedia, it also hosts other related projects and MediaWiki, a wiki software. The Wikimedia Foundation was established in 2003 in St. Petersburg, Florida, by Jimmy Wales as a nonprofit way to fund Wikipedia, Wiktionary, and other crowdsourced wiki projects that had until then been hosted by Bomis, Wales's for-profit company. The Foundation finances itself mainly through millions of small donations from Wikipedia readers, collected through email campaigns and annual fundraising banners placed on Wikipedia and its sister projects. These are complemented by grants from philanthropic organizations and tech companies, and starting in 2022, by services income from Wikimedia Enterprise. The Foundation has grown rapidly throughout its existence. By 2022, it employed around 700 staff and contractors, with annual revenues of $155 million, annual expenses of$146 million, net assets of $240 million and a growing endowment, which surpassed$100 million in June 2021. The Wikimedia Foundation's mission is "to empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally." To serve this mission, the Foundation provides the technical and organizational infrastructure to enable members of the public to develop wiki content in multiple languages. The Foundation does not write or curate any of the content on the wikis itself. This is done by volunteers, such as the Wikipedians who create and maintain Wikipedia. It does collaborate with a network of individual volunteers and affiliated organizations such as Wikimedia chapters, thematic organizations, user groups and other partners in different countries all over the world, and promises in its mission statement to make useful information from its projects available on the internet free of charge in perpetuity.
