NEW YORK, Oct 04, 2005 /PRNewswire-FirstCall via COMTEX/ --  SIRIUS Satellite Radio (Nasdaq: SIRI) today announced it added more than 359,000 new net subscribers during the third quarter of 2005, reflecting continued strong demand for its service. The third quarter net subscriber gain represents a 97% increase in net subscribers over year-ago quarter net additions of approximately 182,000. SIRIUS ended the quarter with over 2.17 million subscribers.

"We continued to experience strong subscriber growth during the third quarter, which was the best third quarter in our history, and increased our market share from the year-ago quarter by more than 20%. With the traditionally heavy holiday selling period coming up, we fully expect demand for our service to accelerate significantly through the remainder of the year," said Mel Karmazin, CEO of SIRIUS. "With the recent introduction of our new programming line-up, which will include Martha Stewart Living Radio later this year and Howard Stern in January 2006, we are ushering-in an exciting new chapter in satellite radio. Plus, we are launching a new generation of products this fall that will complement our unique mix of content and make it very affordable for consumers to subscribe to SIRIUS."

SIRIUS expects to reach three million subscribers by the end of 2005.
