Big picture

Time period Development summary More details
c. 1st century CE – 1990s Intellectual and technological precursors to a universal encyclopedia Efforts to compile universal knowledge long predate Wikipedia. Early encyclopedic works such as Pliny the Elder’s Naturalis historia and the 18th-century Encyclopédie establish the idea of systematically organizing knowledge. Later thinkers including Paul Otlet, H. G. Wells, and Vannevar Bush propose global knowledge systems enabled by modern communication technologies. Late-20th-century developments—including hypertext systems, the free-software movement, and early digital encyclopedias—created the intellectual and technological foundations for a collaboratively edited online encyclopedia.
2000–2003 Creation of Wikipedia and early community formation Wikipedia emerges from the Nupedia project, a free online encyclopedia launched in 2000 using expert peer review. In January 2001 Jimmy Wales and Larry Sanger launch Wikipedia as a wiki-based complementary project to accelerate article creation. The open editing model quickly attracts contributors, language editions expand, and core principles such as the neutral point of view are established. In 2003 the Wikimedia Foundation is created to support the growing project and its related initiatives.
2004–2014 Rapid global growth and institutional consolidation During the mid-2000s Wikipedia expands rapidly in content, readership, and international reach. New language editions proliferate, the proportion of English articles declines, and technical features such as categories, MediaWiki improvements, and Wikimedia Commons strengthen the platform. The community develops governance systems such as the Arbitration Committee and policies including the Biographies of Living Persons rule. Wikipedia becomes one of the most visited websites in the world and a major reference resource for millions of readers.
2015–onwards Mature global knowledge platform and evolving challenges In the later period Wikipedia functions as a mature global knowledge infrastructure. Milestones include billions of edits, large-scale data initiatives such as Wikidata, and widespread use for real-time information during major events like the COVID-19 pandemic. The platform continues to evolve technically through mobile editing tools, interface redesigns, and structured data systems. At the same time, debates arise over censorship, misinformation, artificial intelligence use, and community governance as Wikipedia enters its third decade.

Wales and Sanger created the first Nupedia wiki on 10 January 2001. The initial purpose was to get the public to add entries that would then be "fed into the Nupedia process" of authorization. Most of Nupedia's expert volunteers, however, wanted nothing to do with this, so Sanger decided to launch a separate site called "Wikipedia". Neither Sanger nor Wales looked on Wikipedia as anything more than a lark. This is evident in Sanger's flip announcement of Wikipedia to the Nupedia discussion list. "Humor me", he wrote. "Go there and add a little article. It will take all of five or ten minutes". And, to Sanger's surprise, go they did. Within a few days, Wikipedia outstripped Nupedia in terms of quantity, if not quality, and a small community developed. In late January, Sanger created a Wikipedia discussion list (Wikipedia-L) to facilitate discussion of the project.

I was more or less offered the job of editing Nupedia when I was, as an ABD philosophy graduate student, soliciting Jimbo's (and other friends') advice on a website I was thinking of starting. It was the first I had heard of Jimbo's idea of an open content encyclopedia, and I was delighted to take the job.
