Herbert Marshall McLuhan (July 21, 1911 – December 31, 1980) was a Canadian philosopher of communication theory. His work is viewed as one of the cornerstones of the study of media theory, as well as having practical applications in the advertising and television industries.
McLuhan is known for coining the expressions the medium is the message and the global village, and for predicting the World Wide Web almost thirty years before it was invented. Although he was a fixture in media discourse in the late 1960s, his influence began to wane in the early 1970s. In the years after his death, he would continue to be a controversial figure in academic circles. With the arrival of the internet, however, there was renewed interest in his work and perspective.
