In 1989, CERN was a hive of ideas and information stored on multiple incompatible computers. Tim Berners-Lee envisioned a unifying structure for linking information across different computers, and wrote a proposal in March 1989 called “Information Management: A Proposal”. By 1991, this vision of universal connectivity had become the World Wide Web! To celebrate 30 years since Tim Berners-Lee’s proposal and to kick-start a series of celebrations worldwide, CERN will host a 30th anniversary event on the morning of 12 March 2019 in partnership with the World Wide Web Consortium (W3C) and the World Wide Web Foundation. This anniversary event will be webcast.
