Joshua Meyrowitz quotes:

Truly different behaviors require truly distinct situations.

People are more likely to search for specific books in which they are actively interested and that justify all of that effort of reading them. Electronic images and sounds, however, thrust themselves into people's environments, and the messages are received with little effort. In a sense, people must go after print messages, but electronic messages reach out and touch people. People will expose themselves to information in electronic media that they would never bother to read about in a book.

There is a great difference, then, between "power" and "authority." Power refers to one's ability to coerce others (through physical, economic, or other means) to do one's bidding. One can possess the means of power: physical strength, armaments, and money. But authority must be performed. Authority refers to one's ability to gain the trust and willing obedience of others. While power rests on intimidation, authority survives through inspiration.
