I listened to Howard Stern before he was HOWARD STERN. He was a disc jockey on a local station here in NY. I have followed him all the way to Sirius Radio.
I know people that have worked with him and he is not what you think. He is the smartest man in the media business. He realized when working at the little station that he needed to separate himself from the pack,or just move from station to station scraping by, and he did.
When you listen to the Howard Stern Show you are listening to theater. He is an actor on the radio, and if you really listen you will understand he is very insightful and one of the best interviewers around. In his private life he is very quiet, and when the show goes live, he becomes Howard Stern.
He was probably influenced by Lenny Bruce, George Carlin, and also some of the great talk radio hosts, who are his heroes. He learned his craft from them and spun it.
You would be surprised at his listening audience, many of whom will only admit they listen in private. He represents freedom and verbalizes what many of us are thinking.
