<P> In 1980 , physicist Tim Berners - Lee , a contractor at CERN , proposed and prototyped ENQUIRE , a system for CERN researchers to use and share documents . In 1989 , Berners - Lee wrote a memo proposing an Internet - based hypertext system . Berners - Lee specified HTML and wrote the browser and server software in late 1990 . That year , Berners - Lee and CERN data systems engineer Robert Cailliau collaborated on a joint request for funding , but the project was not formally adopted by CERN . In his personal notes from 1990 he listed `` some of the many areas in which hypertext is used '' and put an encyclopedia first . </P>
