Company On Track to Reach One Million Subscribers by End of Year - SIRIUS Continues to Dominate Satellite Radio Programming With Coverage of the NFL and College Sports, and Unprecedented Commercial-Free Music, Including Eminem's "Shade 45" and Maxim Radio Coming This Fall

NEW YORK - October 19, 2004 - SIRIUS (NASDAQ: SIRI), the premium satellite radio provider known for delivering the very best in commercial-free music and sports programming to cars and homes across the country, today announced that it has surpassed 700,000 subscribers, and remains on track to achieve one million subscribers by the end of the year.

SIRIUS passed the 700,000 mark on October 18, helped by its best month ever on record in September with over 69,000 subscribers.

This fall also marked the debut of SIRIUS NFL Sunday Drive, the programming package that allows subscribers nationwide to hear every NFL game each week, and SIRIUS College Sports Radio, featuring play-by-play coverage of college football and basketball of over 25 top programs from around the country. SIRIUS is also home to 65 channels of 100% commercial-free music as well as over 55 channels of news, sports, weather, traffic information, original entertainment and call-in talk shows, all for the great value of $12.95 a month, with no added premiums, and discounts for advance payments of one-year or more.

"SIRIUS acquired over 69,000 subscribers in September, beating our previous record for monthly subscriber growth," said Joseph P. Clayton, CEO of SIRIUS. "This is indicative of the traction we are seeing in the retail marketplace, and the launch of more factory programs with our automotive partners, as well as the buzz that SIRIUS is generating from exciting programming initiatives such as NFL, college sports, Eminem's 'Shade 45', Maxim Radio and, beginning in 2006, Howard Stern."

SIRIUS also launched a whole new line of smaller, feature-rich satellite radios - such as the 'Sportster' - boomboxes and accessories this fall, which the company says is being well-received by consumers. Plus, SIRIUS also began a new advertising campaign featuring the NFL and commercial-free music programming to support all of its recent initiatives.

SIRIUS and Ford recently announced that Ford will offer SIRIUS as a dealer-installed option in four additional models for a total of 13, and plans to offer SIRIUS as a factory-installed option on up to 20 vehicles over the next two model years.

SIRIUS continues to have the strongest balance sheet in satellite radio, with cash of approximately $800 million.

SIRIUS radios for the car and home beginning at $149 are available at Audio Express, Best Buy, Circuit City, Crutchfield, Car Toys, Good Guys, RadioShack, Sears, Tweeter, Ultimate Electronics, Wal-Mart and thousands of other dealers around the country. SIRIUS radios are also available in select Ford, DaimlerChrysler, BMW, Audi, Volkswagen, Nissan and Infiniti automobiles.
