Harold Innis is known for his insights into mass media.His insights include all of the following except

A) his discussion of time-biased media.
B) his discussion of space-biased media.
C) his recognition that societies are influenced by their dominant forms of communication.
D) that the media influences the mind in largely unconscious ways.

Harold Innis did in fact discuss time-biased and space-biased media, as well as the influence of dominant forms of communication on societies. Therefore, the only option left is D, that Innis did not recognize the influence of media on the mind in largely unconscious ways. However, it should be noted that this concept of unconscious influence was not emphasized by Innis, but it was developed further by later media theorists such as Marshall McLuhan.
