On March 12, 1989 — 25 years ago today — Tim Berners-Lee distributed a proposal to improve information flows at CERN, where he worked. Tim's boss, Mike Sendall, allowed Tim to work on his proposed general software project — developing a universal linked information system that became the "world wide web" — even though the project did not involve high level physics (the focus of CERN). So Tim spent time developing his proposal and wrote the first Internet browser and editor in 1990. By October of 1990, Tim identified 3 fundamental technologies that remain the foundation of today's web:
(1) HTML - Hypertext Markup Language: the publishing language that formats text and structure and allows linking to documents and resources.
(2) URI - Uniform Resource Identifier: an address that is unique for each Web resource.
(3) HTTP - Hypertext Transfer Protocol: a communications protocol that allows for the retrieval of linked resources across the Web.
By 1993, CERN declared that the "world wide web" technology would be made available to everyone on Earth for free, forever.
