Some important information about the history of WWW.
Www was invented in 1989 by Tim Berners-Lee, who worked in the CERN company, in Switzerland. At that time Tim realized that every computer is connected to the Internet, but all computers have information in different formats, which made it difficult to share this information. That's why Tim created the World Wide Web (WWW) which was made publicly available in 1992. Public access to the Internet in India was started on 15 August 1995 by Videsh Sanchar Nigam Limited. Today, India has the biggest dominance on the Internet.
