Tetrad of Internet

        Using Marshall McLuhan’s tetrad concept, I found it very useful to describe any media and analyze its behavior and effects on societies. I choose the Internet as a media to analyze using this tetrad technique:

 §  Enhancement:the Internet amplifies world wide communication and information access instantly

§  Obsolescenc:the Internet reduced the importance of prints, radios, books and even TVs.

§  Retrieval:the Internet returned direct communication.

§  Reversal:the Internet flips the world into one city.
