The line-by-line, sequential, continuous form of the printed page slowly began to lose its resonance as a metaphor of how knowledge was to be acquired and how the world was to be understood. "Knowing" the facts took on a new meaning, for it did not imply that one understood implications, background, or connections. Telegraphic discourse permitted no time for historical perspectives and gave no priority to the qualitative. To the telegraph, intelligence meant knowing of lots of things, not knowing about them.
The idea of taking what people call the 'entertainment culture' as a focus of study, including historical perspective, is not a bad idea.
