Wikipedia Online Encyclopedia Launches
Jimmy Wales and Larry Sanger had launched Nupedia in 2000 as a peer-reviewed free online encyclopedia, but progress was slow due to its rigorous expert review process. On January 15, 2001, they introduced Wikipedia as a complementary wiki-based project allowing anyone to edit articles rapidly. The site went live under the wikipedia.com domain with an initial focus on building content collaboratively, drawing inspiration from open-source software principles. Early policies emphasized neutral point of view and community governance, quickly attracting contributors beyond the small Nupedia team. Within months, Wikipedia expanded to multiple languages and surpassed Nupedia in scale, eventually leading to the latter's closure in 2003.
