Web 1.0 was the term used between 1991 and 2003 to refer to the state of the World Wide Web. It is one-way flow of information through websites which contained "read-only" material for the user. In a few words, Web 1.0 is a retronym which refers to any website design style used before the advent of the Web 2.0 phenomenon.
Since 2004, the term Web 2.0 is the one used to describe those changes that made the Internet the way it is today. The shift from Web 1.0 to Web2.0 can be seen as a result of technological refinements and the evolvement of the behavior of the users.
2.0 sites are interactive and dynamic and the “readers” become a part of the site, because information and opinions can be shared among the creator and/or visitor(s) of the sites. Moreover, people are able to interact with other users with messages, chats, chat rooms or e-mails, being able even to share the content of websites. Some examples of the Web 2.0 phenomenon are social networking sites as facebook, second life, twitter, youtube, blogs, etc.
