History
"Web 2.0" is the result of a brainstorming session between O'Reilly and MediaLive International more particularly with Dale Dougherty and O'Reilly. They noticed that the web took another dimension and so was evoluding because many new original and exciting applications and websites appeared very fastly. They furthermore agreed on the fact that the companies which had survived this evolution to share certain things or thoughts. Perhaps it was the start of a collective thought through the web and it marked a turning point for the "Web 2.0" concept which was materialized with the birth of the "Web 2.0" Conference in october 2004. They listed several principles during this first conference; one of the first important principles was "The Web as a platform".
Since then the term "Web 2.0" has been clearly used, with several million citations in Google. However "Web 2.0" is still a topic for discussions because many people disagree with the definition of this term. Some people just see it as a meaningless marketing buzzword, and some others are delighted with this new revolution and accept it as a new collective thought and source of knowledge.
