Who invented the World Wide Web and proposed it at CERN in 1989?

Tim Berners-Lee invented the World Wide Web and proposed it at CERN in 1989.

Berners-Lee was working as a computer scientist at CERN, the European particle-physics laboratory, when he wrote a proposal for a system to help researchers share information. The Web combined hypertext with the Internet and introduced core technologies including HTML, HTTP, and URLs.

He created the first web browser and web server, and the first website went online in 1991. The Web is not the same thing as the Internet: the Internet is the underlying global network, while the Web is a service that uses linked documents and other resources over that network.

CERN released the Web software into the public domain in 1993. That decision helped the system spread without licensing fees. Berners-Lee later founded the World Wide Web Consortium, or W3C, to coordinate Web standards.
