Wikipedia is a project operated by a non-profit organization, the Wikimedia Foundation, and created and maintained by a strong community of 100,000 international volunteers. Founded in 2001 by Jimmy Wales, Wikipedia has become a top five global Web property according to comScore, but moreover, it has become an indispensable part of our daily lives.
The project is committed to the development of free encyclopedias in all languages of the world and keeping them free and available to everyone, forever. Its sister projects include Wikimedia Commons (a repository of more than 12 million freely usable media files), Wiktionary (a multilingual free content dictionary), and Wikisource (a collection of free source texts). Wikipedia currently offers more than twenty million articles in more than 280 languages. Virtually anyone with Internet access is free to contribute, by providing neutral or cited information.
