Nupedia was a multi-language online encyclopedia whose articles were written by volunteer contributors with relevant subject-matter expertise, reviewed by expert editors before publication, and licensed as free content. It was founded by Jimmy Wales and underwritten by Bomis, with Larry Sanger as editor-in-chief. Nupedia operated from March 2000 until September 2003. It is best known today as the predecessor of Wikipedia. Nupedia had a seven-step approval process to control content of articles before being posted, rather than live wiki-based updating. Nupedia was designed by a committee of experts who predefined the rules. It had 21 articles in its first year, compared with Wikipedia having 200 articles in the first month, and 18,000 in the first year.
