Berners-Lee Proposes World Wide Web: Internet's Blueprint

Tim Berners-Lee, a British software engineer working at CERN in Geneva, published a formal proposal that outlined a system for sharing information across computer networks using hypertext. The document described the architecture of what he called the World Wide Web, a concept so ambitious and so elegantly simple that it would reshape virtually every aspect of human civilization within a single generation. The problem Berners-Lee set out to solve was mundane. CERN employed thousands of physicists from dozens of countries, each using different computers and software. Critical research data was scattered across incompatible systems, and people spent enormous amounts of time simply trying to find information they knew existed somewhere. Berners-Lee had first sketched a solution in a 1989 memo titled "Information Management: A Proposal," which his supervisor famously annotated as "vague, but exciting." The 1990 proposal refined the concept into three foundational technologies. HTML, a markup language for creating documents with embedded links. HTTP, a protocol for transmitting those documents between computers. And URLs, a universal addressing system for locating any resource on any connected machine. Together, these three inventions created a system where any document could link to any other document, anywhere in the world, with a single click. Berners-Lee built the first web server and browser on a NeXT computer at CERN, going live on December 20, 1990. The system was initially used only within CERN, then opened to other research institutions in 1991 and to the general public in April 1993. By the mid-1990s, the web had exploded beyond anything its creator imagined. Critically, Berners-Lee and CERN chose not to patent or charge licensing fees for the web's core technologies. That decision to keep the platform open and free was arguably the single most consequential intellectual property choice in modern history, enabling the explosion of innovation that followed.
