Ward Cunningham created the first wiki in 1995 as a quick way to collaboratively publish information on the web. Wikis allow any user to easily edit and create pages. Wikipedia is the largest wiki, started in 2001, and now has over 1.2 million articles across 200 languages. Wikis provide a way for distributed teams to collaborate instantly by allowing anyone to edit pages, with version tracking to revert changes, though they require management to prevent spam and vandalism.
