Topic 6- Media Effects Using McLuhan's "Tetrad of Media"

Using McLuhan's "Tetrad of Media" (see diagram below), choose a medium or media application or tool (e.g. newspaper, books, radio, tv, film, internet, computer games, handphone, instant messaging, blogging, online advertising, youtube, facebook etc.) and explain its media effects? Please refer to Week 9's lecture notes plus your own research to discuss this topic.


Media effects can be explored using these four McLuhan's original tetrad questions:

1) What does it extend?

2) What does it make obsolete?

3) What new opportunities does it create?

4) When it overextends, what does it reverse to?

I've attached the video below about how media is an extension of ourselves by McLuhan.
