The term “Web 2.0″ was coined in 1999 by Darcy DiNucci.

In her article, “Fragmented Future” she wrote

“The Web we know now, which loads into a browser window in essentially static screenfulls, 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 screenfulls 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”.

So Web 2.0 attributes that website should do a lot more than to just retrieving the information for the user.
