This rare archival footage of McLuhan speaking to an ABC [Australian Broadcasting Corporation] journalist on his visit to Australia was recorded on 19 June 1977 in Sydney.
ABC Archive notes: "Canadian expert on electronic media, Marshall McLuhan, arrives in Australia to address a seminar on Australian radio. He advocates shortening of TV transmission time and better balance between TV, radio and press. McLuhan speaks about the effect of TV on children."
From other sources we know that he was brought to Australia by Sydney radio station 2SM.
Sadly no record of the interviewer has been kept, though we think she has an NZ accent.
