Tim Berners-Lee, a British computer scientist at CERN, proposed an information management system that would become the World Wide Web. By December 1990, he had developed the key technologies that still form the foundation of today's web: HTML, HTTP, and URLs. The first website went live on August 6, 1991, and in 1993 CERN released the web technology into the public domain, enabling its widespread adoption and transforming global information sharing.
