According to the theory of McLuhan that had been brought out in class, media is a massage. I've found some research from the Internet (which also does bring a huge effect to the society nowadays) saying that in Laws of Media (1988) has written the summarized McLuhan's idea about the media in a concise tetrad of media effects. The tetrad is a means of examining the effects on society of any technology (any medium) by dividing its effects into four categories and displaying them simultaneously. McLuhan designed the tetrad as a pedagogical tool, phrasing his laws as questions with which to consider any medium:
-what does the medium enhance?
-what does the medium make obsolete?
-what does the medium retrieve that had been obsolesced earlier?
-what does the medium flip into when pushed to extremes?
The example that i want to bring out according to the theory is blogging, which what I am doing now. Blogging since few years ago start to be so popular in society. It's free for any user to create their own blog and provides unlimited space for users to write their journal and insert anything they want including video clip and music on net. It considers no privacy at all which means anyone on earth can stop by and have a look at each other's blogs.
Let's me 'tetrad' it:
-Enhancement: as I've mentioned above, it provides unlimited space for users to write their journal and insert anything they want including video clip and music on net. It provides a space for the people from the world wide to share their life. Unlike a 'paper' like diary, it contains no other thing but words and some picture (sometimes...) It's dull!!
-Obsolescence: blogging reduces the using of paper. At the same time, it reduces the importance of protecting one's privacy as it consider no privacy once you've posted something on blog. Everyone can view it.
-Retrieval: Blogging continue the habit of writing journal. Nowadays, everyone is so busy to make both ends meet. There is no way for them to continue their habit of writing a journal. Thus, blogging replaces it. It is free and easy to use. While you are having a tough day in working, try to express it in blog. Plus, you will get a positive comments that make your mood gets better. It's about sharing of one's feeling and communication.
-Reversal: Since blogging is being used widely and anyone of us can view it anytime and anywhere, blogging is not only about writing a journal, sometime it could have been included in any learning process. For example, as what I am doing now, students could assess their assignment via blog. It requires no paper and it can be done in anytime, anywhere. Other than that, some of them even sell their product in their blog. Thus, blogging flips into commercial use. They do business and earn money via blogging as it is free.
