World wide web

In 1980, while working at CERN, the European Organization for Nuclear Research, he first described the concept of a global system, based on "hypertext" (text displayed on a computer screen with references, called hyperlinks, to other text that the reader can immediately access). This allowed researchers anywhere in the world to share information via the internet, a computer network that had existed since the 1960s.
