The web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world. Tim Berners-Lee, while working at CERN, implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the internet, so he invented the World Wide Web (WWW) in 1989.
The WorldWideWeb (W3) is a wide-area hypermedia information retrieval initiative aiming to give universal access to a large universe of documents. Here, you can find all the info about the first operative website and, also, you can browse the first website, both with a modern technology compatible page or with a line-mode browser simulator (so you’ll be pushed back to eighties). Again, on the home of the first website, you can know more about the birth of the web and about the CERN, the physics laboratory where the web was born.
This is the link to the official CERN home of the first website in history: http://info.cern.ch/.
