SIRIUS SATELLITE RADIO'S PROGRAMMING RECEIVES TOP HONORS FROM THREE MAJOR MAGAZINES


SIRIUS Recognized by Men's Fitness, New York and Cargo as Having the Best Programming in Satellite Radio


NEW YORK - April 15, 2005 - SIRIUS Satellite Radio (NASDAQ: SIRI) today announced that it has been selected as having the best programming in satellite radio by three top-tier publications: Men's Fitness, New York and Cargo.


In the May issue of Men's Fitness, SIRIUS was selected as the overall winner in a head-to-head competition and proclaimed "the shining star" in satellite radio. SIRIUS was also named the leader in four key categories including hardware selection, exclusive sports coverage, big-name talent and programming. For the programming category in satellite radio, Men's Fitness proclaimed, "SIRIUS is the hands-down winner, with a better mix of music, talk, and sports."


In an article in New York's April 11 issue entitled, "The Well-Wired Home," the magazine advised, "Most of you will want to choose SIRIUS...the programming is superior."


"SIRIUS is dedicated to delivering the best programming in satellite radio, and the recent reviews by these highly respected magazines are very gratifying," said Scott Greenstein, SIRIUS President of Entertainment and Sports. "We believe that creative and innovative programming is what sets SIRIUS apart from the competition, and we will continue to bring the best music, news, information, sports, talk and entertainment to our growing number of listeners across the country."


In addition, Cargo Magazine compared the satellite radio providers in its May issue and gave SIRIUS an "A" for content in its report card of satellite services - the only "A" given in the "Final Grades." Cargo wrote, "Music lovers will appreciate the huge diversity on the dial. Extra credit for signing high-profile contracts with the NFL, Eminem, and Howard Stern, thus ensuring that fans will have exactly what they're looking for."


SIRIUS radios for the car and home are available at electronics and general merchandise stores around the country. For more information, go to www.sirius.com.
