Some of the things he's been saying on the air about terrestrial (public) radio and his promoting of satellite radio has created some strained relationships and ruffled feathers.
There's obviously a tremendous amount of tension between him and Infinity and it's getting closer and closer to the witching hour where he's going over to Sirius Satellite Radio, ... So many are watching, from stock watchers to radio programming watchers. It's ripe for rumors.
There's no question in my mind that satellite radio will take its place in the evolution of radio and that Howard Stern is a catalyst for it happening faster. But it's not going to replace FM or AM radio.
