In the beginning, the World Wide Web was introduced as a medium for sharing scientific and research documents, especially, among government organizations and academic institutions. But with the passage of time, it evolved and crossed the limits defined for it. Initially, until 1990, the World Wide Web (WWW) remained within the boundaries of the European Organization for Nuclear Research (a research organization) known as CERN, but by 1991, it became available to anyone using the internet.
Evolution of the web from Web 1.0 (The World Wide Web) to Web 2.0 (The Social Web) and then to Web 3.0 (The Semantic Web) is shown in the following figure.
