New Delhi: Google on Tuesday celebrated 30 years of World Wide Web (WWW) with a doodle.
British computer scientist Tim Berners-Lee invented the WWW in 1989 and wrote the code for the first web browser in 1990.
Working at CERN in Switzerland, Berners-Lee laid out the basic concepts of the WWW in a proposal, which included ideas like HTML, URL and HTTP.
In a document titled "Information Management: A Proposal", he envisioned the use of hypertext to link documents.
The WWW, commonly known as the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs).
The first web browser was released in 1991 -- initially to the research institutions and then to the general public on the Internet, in the same year.
The web was made public in April 1993. Its popularity started spreading from November with the launch of Mosaic, the first search engine to accept pictures. That revolutionised the web, making it user friendly.
Later on, Mosaic was replaced by the likes of Internet Explorer, Google Chrome and Mozilla Firefox.
The WWW is the primary tool, billions of people today use to interact on the Internet.
In addition to text, web pages may contain images, video, audio and software components that are rendered in the user's web browser as coherent pages of multimedia content.
Before the WWW, remote computers communicated directly for the first time in 1969 and in 1983, TCP/IP standard was adopted.
Thanks to the web as half the world’s population went online in just three decades.
