I believe many forget this book was written in 1964, before your personal computer and cable television. This book, however dense at times and in my opinion, predicted the explosive of the internet and modern electronic media 30 years previous. For anyone who claims the ideas about the tribal structure are false, need only investigate urban design trends today to see that the large city structure is being abandoned for smaller neighborhoods where people can walk everywhere, quite like they may in a tribe, and how the reintroduction of porches and other features that stimulate neighborhood participation are doing the same. And, if you really want some evidence that Mcluhan could base such an idea on an actually occurrence in his own time, you should read up on housing development in the Orange county of Southern California during the 1950s. A group that included the Eames' and others where they were trying to establish such a tribal urbanism, but the commuter culture was established and thus ruled, people fearing change. All that remained of their ideas were thousands of glass houses that no longer meet building code 22 and the commuter culture led to bad ideas like Brasilia, Brazil. Apparently Mcluhan was just the only person to write it down as society quashed it to remain in the safety of the old. I'm sorry but this book is utterly amazing. I look at everything differently now, everything. It makes a lot of sense if you think about it and apply it. And then you realize it was written in the 60s? Wow. Mcluhan was right on target. For those wanting an intro to Mcluhan and have small attention spans I suggest 'On Mcluhan: Forward Through the Rearview Mirror'. I am saddened that I can't attend the Center for Culture and Technology. If you are a person who wants to understand the world so much more clearly READ THIS BOOK, NOW! Another review claims that this book will be looked back on as silly 60s trash. Hmmm NO! I am only eighteen years old, never lived during the 60s, and I'm afraid I can see it is all extremely accurate now and can apply everything Mcluhan says to my everyday life and it makes things make allot more sense. READ THUS NOW. And if you wish to be more enthralled read [the] interview... with the real Bob Dobbs ( not of the church of the subgenius fame). I'm sorry anyone who doesn't like this book or, rather i should say, can't see it as prophetic and right not not worthy of at least my respect if not most people's. Sorry if harsh, but very true.
