In the early 1960s, McLuhan wrote that the visual, individualistic print culture would soon be brought to an end by what he called "electronic interdependence": when electronic media replace visual culture with aural/oral culture.

McLuhan believes that "there can only be disaster arising from unawareness of the causalities and effects inherent in our technologies

McLuhan contrasts the considerable alarm and revulsion that the growing quantity of books aroused in the latter seventeenth century with the modern concern for the "end of the book"
