Innis developed the idea of time- and space-bias to describe the way in which the media operate in society: time-biased media favour the preservation of knowledge over long periods of time, whereas space-biased media favour the dissemination of knowledge over great distances. The bias of communication directly influences the way media exert control and, consequently, the way society is organized.
