Bill Kovach, former editor of The Atlanta Journal and Constitution from 1986 to 1988, says that the paid for advertising radio as we know it today subsequently shaped television when it came to be. It is changing the world, even the whole concept of the nation state is changing. Sander Vanocur says that Roselvelt knew how to create a hearthstone for thirty million people. The radio was a unifying instrument for the whole country. There was a strength of the voice.
Today there is a dilution of voice.
This will cause us problems for democracy because there is a tower of babel for communication. Mike Godwin says there are two ways to unite people. The first is through shared experience. Then people had opportunity to listen, but not to speak. When the constitution was crafted the cost of speaking was relatively low.
