11/29 summary

McLuhan-media contains a kind of message

central culture(HIGH?)
popular culture(LOW?)

why we call it 'central'?
actually they are almost 'edge'.
usually people say than only a small number of people, so-called the wealthy classes enjoy this part.
then, the history and research is not a reason of this situation.
I think the culture doesn't have the classes, but we are divide the culture in up and down classes.
it looks like just the vanity of capitalism.
