Howard Stern is prepared to put up a fight as rumors swirl that the media personality's SiriusXM radio show will be ended indefinitely after his $500 million contract ends

He's back! Howard Stern made an unscheduled appearance on SiriusXM a day after it was reported that his show would be canceled.

All of those rumors come from a story published by The U.S. Sun which said that the satellite radio and streaming provider would not re-up Stern when his contract runs out at the end of the year. Instead, according to the report, SiriusXM would look to make a deal with Stern for his catalogue.
