Reading Marshall McLuhan's ideas this late in the game, they can seem banal because they so accurately describe the way we live today. Like watching a D. W. Griffith movie and trying to get your head around a time when a close-up was a big deal. Two things to remember about him: First off, Canadian. Like Howie Mandel and Bachman-Turner Overdrive. The second thing is he predicted the Internet and coined the term Global Village, which you should think about when you worry about online privacy because one thing about living in a village is everybody knows everybody else's business.
