In the beginning, World Wide Web was introduced as a medium for sharing scientific and research documents, especially, between government organizations and academic institutions. But with the passage of time, it evolved and crossed the limits defined for it. Initially, till 1990, the WWW(World Wide Web) remained within the boundaries of CERN (a research organization), but by 1991, it became available to anyone using the internet.
Evolution of 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:
Web 1.0 - The World Wide Web (1990 - 2000)
- Limited mostly to static websites
- Mostly publishing / Brochure-ware. Limited to reading only for majority.
- Proprietary and closed access
- Corporations mostly, no communities

Web 2.0 - The Social Web (2000 - 2010)

Web 3.0 - The Semantic Web (2010 - onward)

Let's see how long Web 3.0 will go and what more will come with Web 4.0 (the Intelligent Web).
