We use electric lights to break the tyranny of day and night. We use heating and air-conditioning to thwart the cycle of the seasons. Our technology has separated us from the natural rhythms of our world. Just as technology was developed to control nature, media was developed to control populations. It is the science of coercion through TV, radio, print, and advertising.
Public relations means control of a public.
A programmer uses media to influence buying habits in the same way a farmer might use fertiliser to influence the growth of his crop. But, like over-aggressive farmers who erode their own topsoil, these public relations people did their job a bit too well. We fell in love with media itself, and began to value the processes of broadcasting more than any particular message. Eventually, we had so much media that no one could control it any longer. It was everywhere, and sending information back and forth in every direction.
