Tim Berners-Lee proposes the World Wide Web

By the late 1980s the Internet could move data between networks efficiently, but sharing documents across different computer systems at CERN still meant dealing with incompatible file formats and no common way to link one document to another. Tim Berners-Lee proposed a system combining hypertext, documents containing clickable links to other documents, with the Internet's existing networking, so that information stored on different machines could be connected and browsed without everyone using the same hardware or software. The proposal defined the ideas that became HTML, HTTP and the URL, giving the existing Internet infrastructure a simple way to present and connect information for ordinary users rather than only specialists moving files by hand.
