SIRIUS Satellite Radio Programming Named Satellite Radio's Best By Edmunds.com

SIRIUS Receives Nod for Best Rock, Sports, Talk, Entertainment and Overall Programming

NEW YORK, Dec. 15 -- SIRIUS Satellite Radio's programming has been selected as satellite radio's best by the popular and respected automobile information site Edmunds.com. Founded in 1966, Edmunds.com is an internet automotive resource for consumers with more than 4.3 million unique visitors per month.

Edmunds.com conducted a 60-day listening test between the two leading satellite radio services and reported their results in an article now available on their web site. In addition to best overall programming, SIRIUS beat or tied its competitor in five of seven sub-categories, including Rock, Hip-Hop/R&B, Country, Sports, and Talk/Entertainment. In the key Rock programming category, Edmunds.com said "Providing the biggest surprises (to listeners), SIRIUS wins the all-important category."

"It's always rewarding when a respected independent source like Edmunds.com conducts an extensive review and determines that SIRIUS Satellite Radio offers subscribers the best programming in satellite radio," said Scott Greenstein, SIRIUS President of Entertainment and Sports. "We will continue to strive to deliver the best listening experience to our present and future subscribers."

When answering the question "So who's the winner?," Edmunds.com gave the nod to SIRIUS, stating that "The overall win goes to SIRIUS for its edgier and more surprising content, and its better choices in sports and talk."

In the past year, SIRIUS signed top talent for their talk and music channels including the "King of all Media," Howard Stern, who will join the company January 1, 2006, Eminem, Lance Armstrong, Bill Walton, Tony Hawk and many more. In addition, SIRIUS broadcasts play-by-play games of the NFL, NBA and 27 of the nation's premier colleges. As the official satellite radio partner of the NFL, SIRIUS broadcasts every game of the NFL season, which can be heard anywhere in the country.

In addition to the Edmunds.com article, SIRIUS products have been included in holiday gift guides in several top publications including Newsweek and Entertainment Weekly.
