Marshall McLuhan was a Canadian philosopher, who was famously known for his theories on media and communication. He coined the term "the medium is the message" which suggests that the form in which a message is conveyed is equally as important as the message itself, and can affect how it is interpreted. Synonyms for Marshall McLuhan often include "media theorist", "communications philosopher" or simply "media scholar". His works have had a profound impact on the field of media studies and continue to shape our understanding of modern communication. McLuhan remains an important figure in understanding the effects of technology on society and culture.
