SIRIUS Shines With Uninterrupted Service During Blackout

Satellite Radio Broadcaster Provides Support to Partners and Live Information for SIRIUS Subscribers

NEW YORK, Aug. 15 -- SIRIUS (Nasdaq: SIRI), known for delivering the very best in commercial-free music and premium audio entertainment, today announced that the company's broadcast operations were not affected by yesterday's historic blackout due to SIRIUS' advanced broadcast technology. SIRIUS aired special announcements on all 100 news, talk and music streams, alerting listeners to tune to SIRIUS' news streams for immediate information. SIRIUS carried live coverage on the Company's talk and news streams, including live reports from the streets of New York City.

"During the past 24-hours, New York City residents and all of those affected by the blackout have shown courage and patience in coping with this ordeal. SIRIUS listeners were able to follow the events live, as they were happening, providing them with a sense of comfort during times of uncertainty," said Joseph P. Clayton, president and CEO, SIRIUS. "The blackout provided solid proof that our technology is not only prepared for any type of situation, but that we can use it to provide broadcast support to our partners in times of need."

"When the blackout occurred, our back-up generators immediately responded and provided support to our broadcast and studio facilities," said Terry Smith, chief technology officer, SIRIUS. "The SIRIUS subscriber experience was not interrupted at any point during the blackout; in fact, we have heard from many subscribers that SIRIUS was their only source of live information during the crisis."

"During the blackout, SIRIUS subscribers never lost touch with the breaking news and events taking place in the Northeast. We carried more than nine hours of live interviews from New York City's Times Square on SIRIUS OutQ. We also carried live coverage from our news partners including , CNN, CNBC, ABC, E! Entertainment, BBC and the Associated Press," said Jay Clark, executive vice president programming SIRIUS. "We provided additional broadcast support to a number of our partners and to WNYC (NPR Radio), which was without power at its downtown studio location."
