About Wikimedia Foundation, Inc.

Want free access to the sum of all human knowledge? Wikimedia Foundation can give it to you. The not-for-profit organization has produced a plethora of free-content wiki projects, including one of the most visited sites on the Internet, online collaborative encyclopedia Wikipedia (the foundation's first project). The term wiki (a Hawaiian word for "fast") describes a collection of Web pages designed to enable anyone with Internet access to contribute or modify content. Wikimedia has a paid staff of about 280, while hundreds of thousands of volunteers contribute content. The Wikimedia Foundation is funded primarily through donations and grants, and was founded by Internet entrepreneur Jimmy Wales and philosopher Lawrence Sanger in 2001.
