Who invented the World Wide Web in 1989?

Tim Berners-Lee invented the World Wide Web in 1989.

While working at CERN, the European particle physics laboratory near Geneva, Berners-Lee proposed a system for sharing information across computers. He developed the core technologies of the Web: HTML for page structure, HTTP for transferring pages and URLs for addressing resources. He also created the first web browser and web server.

The Web is often confused with the internet. The internet is the global network infrastructure; the Web is a service that uses that infrastructure to connect linked documents and other resources. Berners-Lee made the Web freely available without patent royalties, a decision that helped it spread rapidly. CERN placed the software in the public domain in 1993.
