Abstract

This paper, first presented at the spring 1990 conference on Mass Media Ethics in the Information Age, compares and contrasts approaches of five scholars - Harold Innis, Marshall McLuhan, Walter Ong, Neil Postman, and Jacques Ellul - whose works are chief contributions to an influential communications theory that posits that the history of media technologies is central to the history of civilization, that media transformations result in social change, and that changes in the form of media technology alter the structure of consciousness.
