Update: After posting on the MEA listserv that Bob's video was available on YouTube, his response included the following, which serves as an emendation to what I wrote above:
Under the tutelage of professors Neil Postman, Terry Moran and Christine Nystrom, it was the practice in the 1970's at New York University's Program in Media Ecology Conferences for each doctoral class to pick one member to deliver a "State of the Class" address. (Archivists alert! I still have some of the original material from these conferences as well as materials handed out in class by Postman, Moran, Nystrom and others.) At the fall 1976 conference my "Class of 1977" decided to do something different. I had access to a Sony Betamax 1/2-inch, reel to reel, black and white recorder and a camera, and so instead of one class member giving a 30 minute address, each of us in the Class of '77 prepared up to five minutes on video tape of our own personal metaphor for "What is Media Ecology?" "A Model Media Ecologist" was my contribution. (I have the complete video of the Class of '77 if anyone is interested.) I sang it to the tune of Gilbert & Sullivan's "A Modern Major General." You'll notice there is no mention of personal computers (the Macintosh was just a gleam in Steve Job's eye), nor CD's, DVD's, nor even video discs. That's an IBM Selectric in front of me. On the shelves behind me is the complete LP collection of NYU's Loeb Student Center. (Younger list members can query older ones for a description of what an LP was.) These were primitive times and we were all pioneers!
