Wikipedia is a free, web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Launched on January 15, 2001, by Jimmy Wales and Larry Sanger, it is designed to be a freely accessible and editable repository of knowledge. Wikipedia is one of the largest and most popular general reference works on the internet, with millions of articles in various languages.

History

Wikipedia began as a complementary project to Nupedia, a free online encyclopedia with a more traditional editorial process. The idea for Wikipedia was conceived by Jimmy Wales and Larry Sanger to create a more open and participatory model of knowledge creation. Unlike Nupedia, which required expert review and was slow to develop, Wikipedia allowed anyone with internet access to contribute and edit articles, rapidly accelerating its growth and expansion.

Initially, Wikipedia was launched in English, but its success soon led to the creation of versions in other languages. The first non-English version, the German Wikipedia, was launched in March 2001, just a few months after the English edition. This rapid expansion into multiple languages was facilitated by the wiki model, which allowed volunteers from around the world to create and edit content in their native languages.

In 2003, the Wikimedia Foundation was established to support Wikipedia and its sister projects, including Wikimedia Commons and Wiktionary. The foundation provided organizational structure and resources, helping to sustain and grow the Wikipedia project. This period marked the beginning of Wikipedia's transition from a grassroots initiative to a major global institution.

The mid-2000s saw significant developments in Wikipedia’s infrastructure and policies. In 2005, the Wikimedia Foundation implemented the "Neutral Point of View" policy to address concerns about bias and to ensure that articles presented information in a balanced manner. This policy was a key step in enhancing the credibility of Wikipedia and distinguishing it from other sources of information.

By 2007, Wikipedia had achieved a significant milestone with its 2 millionth article. This period also saw the introduction of new features, such as the "edit" button on articles, which simplified the editing process for users. The introduction of these features contributed to Wikipedia's growing user base and the increasing amount of content available on the platform.

In 2010, Wikipedia celebrated its 10th anniversary, marking a decade of unprecedented growth and influence. The event highlighted the project’s achievements and the contributions of its global community of editors. During this time, Wikipedia had become one of the most visited websites in the world, reflecting its widespread impact on information access and public knowledge.

In recent years, Wikipedia has continued to evolve, incorporating new technologies and adapting to changes in the digital landscape. The platform has explored ways to enhance content quality through machine learning and artificial intelligence, while also addressing challenges related to misinformation and vandalism. The commitment to maintaining an open and collaborative environment remains central to Wikipedia’s mission, ensuring that it continues to be a valuable resource for users around the world.
