Bomis, was a dot-com company best known for supporting the creations of free-content online-encyclopedia projects Nupedia and Wikipedia. It was co-founded in 1996 by Jimmy Wales, Tim Shell, and Michael Davis. By 2007, the company was inactive, with its Wikipedia-related resources transferred to the Wikimedia Foundation.

Wikipedia is a free content online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and the use of the wiki-based editing system MediaWiki. Wikipedia is the largest and most-read reference work in history. It is consistently ranked as one of the ten most popular websites in the world, and as of 2024 is ranked the fifth most visited website on the Internet by Semrush, and second by Ahrefs. Founded by Jimmy Wales and Larry Sanger on January 15, 2001, Wikipedia is hosted by the Wikimedia Foundation, an American nonprofit organization that employs a staff of over 700 people.
