From the late 1960s to the early 1990s, the Internet was a communication and research tool used almost exclusively for and military purposes. This changed radically with the introduction of the world wide web (WWW) or web in short in 1989. The WWW is a set of programs, standards and protocols governing the way in which multimedia files ( multimedia files are the documents that contain a combination of text, photographs, graphics, video and audio ) are created and displayed on the Internet. Before WWW, Internet was mainly used for obtaining textual information. But post-WWW, the Internet popularity grew tremendously because of graphic-intensive nature of WWW. Therefore, we may attribute the explosion in use and popularity of Internet to WWW only. The World web (WWW) is also affectionately called "The Web" WWW was proposed between 1989-1991 by Tim Berners-Lee. Proposed in 1989, WWW became a reality with invention of HTML and a text browser in1990.
