Competition. One drive time guy I listened to was forbidden by the suits to mention satellite radio at all, so he called it the magic radio, usually in reference to the oldies stations and the like if somebody was in the news, like from dying.
Not that you bring it up, Stern caused a lot of problems when leaving for satellite radio, continually pimping his move (from CBS?).
When Howie Carr was an employee of WRKO he used that description....”magic radio”.....
