Wikimedia Foundation

The Wikimedia Foundation is the nonprofit organization that provides the essential infrastructure for free knowledge. It hosts Wikipedia, the free online encyclopedia written in over 300 languages by volunteers around the world, along with other collaborative projects such as Wikimedia Commons, Wiktionary, Wikidata, and Wikivoyage. The Foundation does not write or edit articles itself; content is created and verified by a global community of volunteers, and the organization is powered primarily through donations. The Foundation serves readers, editors, and researchers worldwide, working toward a world in which every single human being can freely share in the sum of all knowledge. Its open source technology keeps Wikipedia fast, reliable, and accessible.
