"No group of sociologists can approximate the ad teams in the gathering and processing of exploitable social data. The ad teams have billions to spend annually on research and testing of reactions, and their products are magnificent accumulations of material about the shared experience and feelings of the entire community."
Marshall McLuhan
"Publicity is the deliberate attempt to manage the public's perception of a subject. The subjects of publicity include people (for example, politicians and performing artists), goods and services, organizations of all kinds, and works of art or entertainment."
Marshall McLuhan
"[...] All media work us over completely. They are so pervasive in their personal, political, economic, aesthetic, psychological, moral, ethical, and social consequences that they leave no part of us untouched, unaffected, unaltered. The medium is the message. Any understanding of social and cultural change is impossible without a knowledge of the way media work as environments.[...] All media are extensions of some human faculty — psychic or physical. [...] Media, by altering the environment, evoke in us unique ratios of sense perceptions. The extension of any one sense alters the way we think and act—the way we perceive the world. When these ratios change, men change.[...]"
Marshall McLuhan
