"The effect of TV, as the most recent and spectacular electric extension of our central nervous system, is hard to grasp for various reasons. Since it has affected the totality of our lives, personal and social and political, it would be quite unrealistic to attempt a 'systematic' or visual presentation of such influence. Instead, it is more feasible to 'present' TV as a complex gestalt of data gathered almost at random."
