The Stern Effect. Sirius gains some "serious" ground on XM. 

What other radio personality could add over 4 million subcribers to a Satellite Radio company? Other than Howard Stern? Probably no one! Sirius has a way to go before it even matches XM subscriber base. With all of the money they have paid Howard for his 5 year stint, I hope they don't fold before they can become a viable company.
