Herbert Marshall McLuhan', (July 21, 1911 – December 31, 1980) was a Canadian philosopher of communication theory and a public intellectual. 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. In the years after his death, he continued to be a controversial figure in academic circles. With the arrival of the internet, however, there was renewed interest in his work and perspective.
