Sir Tim Berners-Lee

He regarded as inventor of the World Wide Web in 1989 while he was working in the Cern.

There are three the key innovations that formed the Web;  HTTP (hypertext transfer protocol); allows you to click on a link and be brought to that document or Web page,  URLs (universal resource locators, which Tim originally referred to as URIs, for universal resource indicators); URLs serve as an address for finding that document or page, and HTML (hypertext markup language); gives you the ability to put links in documents and pages so they connect.

Tim Berners Lee has a analogy between web and  market economy:

“anyone can trade with anyone else without having to go to a physical market square to do it. The traders just need to know the rules. The hardest thing for people to grasp about the Web is that it has no center; any computer (or node, in mathematical terms) can link to any other computer directly, without having to go through a central connection point. They just need to know the rules for communicating.”
