From Duarte: Marshall McLuhan was one of the earliest scholars to discuss the changing nature of media in the electronic age and today would have been his 100th birthday. Famous for coining the phrase “the medium is the message,” he devoted a great deal of attention to explaining how television changed the way the audience understands and participates in content. In his commentary on the landing of Sputnik, he called this new type of viewer a “simultaneous man” who prefers “flexibility and diversity” and lives in a “global theatre.” “On Spaceship Earth there are no passengers; everybody is a member of the crew.” He unpacked some of these ideas on the television program Our World in 1967. · Go to If the medium is the message, would McLuhan like PowerPoint? →
