What was Nupedia?

Nupedia was an English-language online encyclopedia^[1] founded by Jimmy Wales^[1] in 1999, with a goal of creating high-quality articles written by experts and approved through a seven-step review process. It operated until 2003 and is best known as the predecessor of Wikipedia. Nupedia had a peer-review process and was not a wiki, requiring scholarly volunteer contributions and aimed for content comparable to professional encyclopedias. However, it struggled to attract contributors and ultimately declined in relevance due to the success and development of Wikipedia.
