Wikipedia Online Encyclopedia Launches

Context

Printed encyclopedias had long depended on panels of recognized experts and lengthy editorial oversight, a model carried into early digital efforts such as Microsoft Encarta. Web-based experiments in the 1990s, including the short-lived Interpedia proposal, explored collective authorship but never produced substantial content. Richard Stallman’s 1998 call for a freely editable universal encyclopedia underscored the appeal of removing centralized gatekeepers.

In 2000, entrepreneur Jimmy Wales established Nupedia through his company Bomis, hiring philosopher Larry Sanger as editor-in-chief. Nupedia required qualified volunteers to submit articles that underwent a multi-stage expert review, resulting in only a dozen completed entries after a year. Team members began discussing lighter-weight drafting tools that could feed polished material into the main project.

Wiki software, already used on sites such as Ward Cunningham’s WikiWikiWeb, offered a simple way for multiple contributors to revise the same page in real time. A conversation between Sanger and programmer Ben Kovitz in early January 2001 crystallized the idea of applying this approach to encyclopedia work.

What Happened

On January 2, 2001, Ben Kovitz explained wiki mechanics to Larry Sanger over dinner in San Diego. Sanger posted the suggestion to the Nupedia mailing list, and Wales quickly arranged for a test wiki to be installed. On January 10 the new system appeared under the nupedia.com domain, allowing anyone to create or edit draft articles without prior approval.

Five days later, on January 15, the project moved to its own domain, wikipedia.com, and went live with the first public edit reading “This is the new WikiPedia!” Bomis supplied the server hardware located in San Diego. Wales later recalled making an initial test edit of “Hello, World!” on the platform, though the earliest preserved change is the homepage announcement.

On January 17 Sanger formally announced the new site to the Nupedia mailing list, describing it as a supplementary, independent project intended to speed content creation. Early contributors quickly began populating basic articles on topics ranging from philosophy to computing.

Aftermath

Within weeks the site drew editors who had never participated in Nupedia’s formal process. Growth accelerated through word of mouth and links from technology forums, producing thousands of entries by mid-2001. The English edition alone reached more than 20,000 articles by year’s end, while parallel editions in other languages were opened.

Nupedia’s strict review pipeline could not keep pace, and its content was gradually migrated or abandoned. Sanger departed the project in 2002; Nupedia itself was shuttered the following year. Community norms around neutral point of view and citation requirements began to crystallize in the first months of open editing.

Legacy

Wikipedia grew into the world’s largest reference work, recording billions of monthly page views and serving as a primary information source for students, journalists, and researchers. Its volunteer-driven model demonstrated that large-scale, decentralized collaboration could produce a comprehensive knowledge resource at minimal cost.

The platform’s success also exposed persistent challenges of accuracy, editorial bias, and resistance to vandalism, prompting ongoing refinements in governance, sourcing policies, and technical safeguards. Its example influenced later open-knowledge initiatives in education, science, and cultural heritage.
