Big picture

Time period	Development summary	More details
1994-1999	Early Years	The concept of wikis emerge with Ward Cunningham's creation of WikiWikiWeb. Initially designed as a collaborative tool for software developers, WikiWikiWeb provides a simple yet effective system for sharing and editing information. Its success quickly leads to the development of other wiki applications and websites, demonstrating the potential of this new technology.^[1]
1999–2001	Growth and Tensions	WikiWikiWeb experiences significant growth during this period, attracting a larger user base. However, this growth also brings challenges. Disagreements arise among contributors regarding the focus of the wiki, leading to tensions and the creation of sister sites. These sister sites, such as MeatballWiki, allow for more specialized discussions and help alleviate some of the strain on the main wiki.
2001	Rise of Wikipedia	Wikipedia launches as a free encyclopedia, marking a turning point in the history of wikis. Its success introduces the concept of wikis to a wider audience, demonstrating their potential for collaborative knowledge creation. Wikipedia quickly gains popularity and becomes the most prominent wiki of its time.
2002 – 2006	Democratization	Wikis become accessible for the general population. Many different groups of people with various motivations get together to create hosted wikis, which are wiki engines that are installed and hosted on public servers, removing the administration burden associated with running one's own. However, the growth of wikis is severely limited during this period, as the only way one could use a wiki is to first set up a wiki engine on a server. This means that to use a wiki, one has to have access to a server that is available through the Internet as well as the skills to set up and run a wiki engine.^[1] Between 2004 and 2006, a significant shift occurs. Entrepreneurs recognize the potential in offering hosted wikis, also called wiki farms, which enable users to create wikis without requiring their own servers or technical expertise. With a hosted wiki, anyone can begin immediately. The only necessary skill is knowing how to create and edit wiki pages, a far simpler task than setting up a wiki engine.^[1]
2006	Maturation of Wikis	The period from 2006 onwards marks a significant maturation of wikis. Wiki hosting services become increasingly popular, making it easier for individuals and organizations to create their own wikis. Specialized wikis emerge for various topics, catering to niche communities and interests. Additionally, wikis integrate with social media and other platforms, enhancing their accessibility and collaboration capabilities. However, challenges such as quality control, copyright issues, and commercialization arise. Despite these hurdles, wikis would continue to play a vital role in knowledge sharing, community building, and collaboration.

Ward called it 'the simplest online database that could possibly work'. In 1994, he wanted a quick way to collaboratively publish software patterns on the Web. Ideas that had developed from his work with program development and HyperCard stacks went into it, and the first 'wiki server' was born. ... Wiki shares some history with the use of index cards in object-oriented programming. Both Wiki and CRC Cards credit an unpublished HyperCard stack as their common ancestor.
