Why web 2.0 came into existence when web 1.0 was there?

Web 1.0 was the first version of world wide web (www) revolution. It consisted of different static web pages (interlinked together) hosted on various internet servers. These servers support static web pages containing millions of documents.

These documents are formatted using HTML which is a markup language. Other than text, the web could support hyperlinks, graphics, audio and video files. With static web pages, the role of users was limited to viewing and downloading the content.
