Walter Ong's book "Orality and Literacy :the technologizing
of the word" is a good introduction to the effects of
technological change on communication. He starts by
examining the effects of written technology on oral
communication and cultures and continues with an examination
of the possible effects of high technology on cultures and
communication. I also suggest "The Mode of Information" by
Mark Poster which examines the effects of high-tech on
society from a literary and cultural theory perspective.
The Laws of Media came out about 2 years ago. It was jointly written by
McLuhan and his son, Published after his death naturally. It may be more
appropriate to todays technology than Unerstanding Media. It underwhelmed
the critics and went away quickly, but it is good.
