Marshall McLuhan's tetrad of media effects[1] uses a tetrad - a four-part construct - to examine the effects on society of any technology/medium (that is, a means of explaining the social processes underlying the adoption of a technology/medium) by dividing its effects into four categories and displaying them simultaneously. The tetrad first appeared in print in articles by McLuhan in the journals Technology and Culture (1975)[2] and et cetera (1977).[3] It first appeared in book form in his posthumously-published works Laws of Media (1988)[4] and The Global Village (1989).[5]
