EVOLUTION OF WEB BROWSERS

The concept of the browser was envisioned in the 1960's by Ted Nelson. 
Tim Berners Lee developed WWW by 1991. He then wrote the first web browser which was graphical as well as served as an HTML editor. During 1193 a text-only hypertext browser called Lynx was adapted to support the web.
