After hinting on-air for several months that he may retire, Howard Stern announced this morning on his Sirius XM Satellite Radio show that he has re-signed for five more years.

“On my first day in satellite radio Sirius had approximately 600,000 subscribers," Stern said on-air. "Today, the two companies have 20 million; and, in my view, we have just scratched the surface of how many people will get on board,” Stern said, adding that he was excited that Sirius XM will now have better access on smartphones and other mobile devices.

94 WYSP brought Stern's show to Philadelphia listeners in August 1986 and he was heard on the station until leaving CBS Radio to launch Sirius in January 2006.
