Which person invented the World Wide Web at CERN?

Tim Berners-Lee invented the World Wide Web at CERN.

In 1989, Berners-Lee proposed a system for linking and sharing information across the Internet. He developed the core technologies that made the Web practical: HTML for page structure, HTTP for transferring pages, and URLs for identifying resources.

Berners-Lee created the first web browser and web server while working at CERN, the European particle-physics laboratory. The first website explained the project itself and ran on a NeXT computer.

The Web is not the same thing as the Internet. The Internet is the underlying global network, while the Web is one information system that uses it. Email, online games, and file transfers can operate over the Internet without being websites.
