Marshall McLuhan
Perception theorist who made the medium itself the object of study
McLuhan treated newspapers, television, advertising, print, and electronic media as environments that shape perception and institutions. His key contribution was not predicting a device, but offering a way to interrogate media form, speed, scale, and sensory bias.
