Author Paul Levinson Discusses Marshall McLuhan's Understanding Media

In the following keynote address given at Baylor University, author Paul Levinson discusses Canadian philosopher and academic Marshall McLuhan's seminal book, "Understanding Media: The Extensions of Man," which proposed that the media--not the content that they carry-- affects the society in which it plays a role and, thus, should be the focus of study. Levinson, a colleague of McLuhan's, lays out, how in the decades since its 1964 publication, McLuhan's study of media theory and the concept that "the medium is the message," still holds true.
