"In the United States radio was centralized to maximize advertising revenue; in Britain to preserve and promote the values of the elite; and in Germany to advance Nazi propaganda. Whatever the reason, the result was the most centralized medium in history. In the United States radio listeners were gathered up by networks that saw them as consumers to be sold to; in Britain they were the masses to be instructed and improved; in Germany they were the people to be indoctrinated and misled. In each case there was a striking "us and them" division between broadcasters and the faceless mass of their listeners."
