The traditional audio and video materials have been augmented by multimedia applications. The developments in the field of Web and digital multimedia have provided new opportunities to teachers to engage the learners as active learners. Emergence of Web 2.0 is the most phenomenal of them. Traditionally the World Wide Web (WWW) has been considered as a place to retrieve information.
The information provided through HTML codes and sharing of resources through FTP (File Transfer Protocol) was the main utility. But the drawback was that such flow of information was largely unidirectional. This necessitated the need for some interactivity on the web and tools were developed which would allow the users to add content to the web. Such content could be in the form of text, audio, video, slideshows etc. The communication became bidirectional. The term web 2.0 was first used in 1999 by Darcy DiNucci; but it came into prominence in 2004 when O’Reilly Media hosted the first Web 2.0 conference.

It is an innovative platform where the creative minds meet and discuss or share ideas.
