The term was used for the first time in the 2004, by “Average O’reilly”, a company that among others things organizes conferences of technological topics. In the first conference dedicated to this Web 2,0, certain keys were transformed that characterize to the current: the use of the Internet like a platform, the use of data bases, and the social architecture among others.
In fact levels use different hierarchic in this new Internet or Web 2,0, that goes from the zero for those applications that can operate in line as much as “off line”, to the level 3, that talks about those applications that could not exist without the Internet and the human interaction.
The term Web 2,0 in addition has generated an intense debate, since many think that it is only a new form of publicity for services and already existing applications from the beginnings of the network, like for example in the forums. It is even spoken of “bubble 2,0”, making reference to the collapse of innumerable emergent projects between 1997 and the 2001, when existing a great number of companies developing similar products without counting on a clear model of businesses.
