History of Web 2.0 The term, Web 2.0, first gained currency after the 2001 “dot.
Bomb” when the IT bubble that had lasted a good 5 years burst. While some commentators suggested that the Internet had been over-hyped, other folks maintained that the crash
signaled the end of the first phase of the Internet and suggested that the more exciting stuff was yet to come. They
called this new phase or era “Web 2.0.”
Whether Web 2.0 is substantively different from prior Web technologies has been challenged by World Wide Web inventor Tim Berners-Lee, who describes the term as jargon His original vision of the Web was "a collaborative medium, a place where we [could] all meet and read and write".[On the other hand, the term
Semantic Web (sometimes referred to as Web 3.0
was coined by Tim Berners-Lee for a web of data that can be processed by machines
The term "Web 2.0" was first used in January 1999 by Darcy DiNucci, an information architecture consultant. In her article, "Fragmented Future", DiNucci writes:[4]
The Web we know now, which loads into a browser window in essentially static screenfuls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop. The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens. It will [...] appear on your computer screen, [...] on your TV set [...] your car dashboard [...] your cell phone [...] hand-held game machines [...] maybe even your microwave oven.
What is Web 2.0 ? is the current state of online technology as it compares to the early days of the Web, characterized by greater user interactivity and collaboration, more pervasive network connectivity and enhanced communication channels.
Web 2.0 applications often use advanced web features like AJAX to improve the speed of interaction, the term is more about the type of applications than the technology used. is the term given to describe a second generation of the World Wide Web that is focused on the ability for people to collaborate and share information online. Web 2.0 basically refers to the transition from static HTML Web pages to a more dynamic Web that is more organized and is based on serving Web applications to users.
