Last year, SiriusXM’s Scott Greenstein said on an earnings call, “As for Howard, he’s a singular talent. No one pretended when Johnny Carson or others retired that the new group would replace them. They were just simply filling in on those slots. So Howard, we hope he continues forever.”

Noise about the end of “The Howard Stern Show” at SiriusXM is getting louder, though neither side has provided an official confirmation either way. Still, the speculation is drawing attention from as high up as the president of the United States.
