Explained in plain English

Who owns Wikipedia?

Wikipedia is owned and operated by the Wikimedia Foundation, a non-profit organisation based in the United States. It was founded in 2003 to support Wikipedia and its sister projects, which are all free knowledge resources. The Foundation’s mission is to empower and engage people around the world to collect and develop educational content. This is why it took some systems offline after the PHP flaws.
