Is there Radio?

I found this article very interesting. I know several radio personalities and I must say that they have what is called a, "face for radio." If radio stations increase the demand for video exposure of their hosts soon radio talent will have to have a "look." This will cause a change in radio. I think that the stations will start looking for the faces instead of the best talent. It reminds me of Amos and Andy. When Amos and Andy was on radio the talent was Caucasians but when the show went to television the talent had to change so the men who had made the show famous were done. I am forced to ask this question, "Will great radio talents be replaced by medicore faces?"
