The WikiWikiWeb, or simply WikiWiki or Wiki (with a capital 'W'), is the first ever wiki, written in Perl. It accompanies the Portland Pattern Repository (PPR) on c2.com and is located at c2.com/cgi/wiki. It contains various topics and discussions about software engineering. The term wiki that is used to refer to other similar groups of modifiable Web pages, e.g. Wikipedia, came from this original wiki.
In order to make the exchange of ideas between programmers easier, Ward Cunningham started developing the WikiWikiWeb in 1994 based on the ideas developed in HyperCard stacks that he built in the late 1980s. He installed the WikiWikiWeb on his company Cunningham & Cunningham's website c2.com on March 25, 1995. Cunningham named WikiWikiWeb that way because he remembered a Honolulu International Airport counter employee telling him to take the so-called "Wiki Wiki" Chance RT-52 shuttle bus line that runs between the airport's terminals. "Wiki Wiki" is a reduplication of "wiki", a Hawaiian-language word for fast. Cunningham's idea was to make WikiWikiWeb's pages quickly editable by its users, so he initially thought about calling it "QuickWeb", but later changed his mind and dubbed it "WikiWikiWeb". The WikiWikiWeb's WelcomeVisitors page contains the following description:
This wiki's primary focus is PeopleProjectsAndPatterns in SoftwareDevelopment. However, it is much more than just an InformalHistoryOfProgrammingIdeas. It started there, but the theme has created a culture and DramaticIdentity all of its own. All Wiki content is WorkInProgress. Most of all, this is a forum where people share ideas! It changes as people come and go. If you are looking for authoritative information, try WikiPedia. All the information here is subjective.
Some words are written in CamelCase because this is the syntax used to create inter-page links by WikiWikiWeb's software, Wiki Base.

WikiWikiWeb and its designated sister sites
The WikiWikiWeb plays an important historical role on the World Wide Web and the Internet, because of its influence on other online communities. The WikiWikiWeb's focus on specialized programming makes its content relatively unintelligible to people outside the programming sphere, but, nevertheless, editors (so-called "wiki citizens" or "wikizens") and visitors and readers of the WikiWikiWeb took the idea of making pages user-modifiable outside the WikiWikiWeb and created their own new wiki engines (programs which run wikis) and wikis.
Wiki communities outside the WikiWikiWeb implemented their wiki engines to create wikis focused on content other than programming. The versatility of wikis and their multiple applications is what subsequently made them popular in the Internet's communities.
Probably the most famous example of the WikiWikiWeb's legacy is Wikipedia. A WikiWikiWeb user, programmer Ben Kovitz of San Diego, California, introduced the WikiWikiWeb to Larry Sanger of the Internet company Bomis on the evening of January 2, 2001. At the time, Bomis was working on the online encyclopedia Nupedia, but that project failed, so Sanger suggested running an open encyclopedia on UseModWiki, an indirect clone of WikiWikiWeb's engine. Sanger presented the idea to Jimmy Wales, the then head of Bomis, and he agreed. The UseModWiki-based encyclopedia eventually came to be known as "Wikipedia".
Other popular websites have since come to embrace the wiki method, such as Amazon.com, which in 2007 launched its own Amapedia after two years of trialling wiki technology for customer reviews for items.
