NEW YORK, May 2, 2005 /PRNewswire-FirstCall via COMTEX/ -- SIRIUS Satellite Radio (Nasdaq: SIRI) and PodShow.com announced today that Adam Curry, the "father of podcasting," will produce a special SIRIUS Satellite Radio program which will broadcast the best podcasts in the world exclusively to SIRIUS subscribers.

The program, Adam Curry's PodShow, debuts on SIRIUS on Friday, May 13th. This marks the first collaboration between the two key players in the two most exciting, innovative mediums in audio broadcasting -- satellite radio and podcasting. Curry helped design the digital tools that have made podcasting a worldwide phenomenon.

The four-hour, weekday program will feature highlights and insights from the world of podcasting and will introduce SIRIUS listeners to a completely new range of talent and artists from around the world, including the best new, undiscovered music. The program's SIRIUS debut coincides with the launch of Curry's PodShow.com, the first true entertainment and information network in podcasting.

"Podcasting allows an amazing new group of producers and artists to share their talent and creativity," said Scott Greenstein, SIRIUS President of Entertainment and Sports. "With this new venture, SIRIUS and PodShow.com will bring the best of podcasting's most innovative players and artists directly to SIRIUS subscribers."

Podcasting enables anyone to create and/or host his or her own programming and make it available for others to download to a computer or portable media player. In less than six months, more than six million people have listened to podcasts.

"Podcasting is not just about portable media players," said Curry, the former star MTV VJ who developed podcasting in mid-2004. Explaining how the new collaboration between SIRIUS and PodShow.com takes podcasting to a completely new level, he said, "Podcasting is an entirely new form of broadcasting that enables anyone to create powerful content. By combining the creative talent and content of available podcasting with superior programming of SIRIUS, we can create and showcase talent that terrestrial radio listeners would not be able to hear. We think that this partnership is about introducing the best of podcasting to the world."

Adam Curry's PodShow will begin with four hours of daily programming, which will be heard weekdays exclusively on SIRIUS channel 148. Listeners can expect unique insights into the world of podcasting from its inventor, as well as get a taste of the most popular podcasts -- from engaging talk to outrageous comedy to the hottest music in podcasting. In another first, listeners to the program will be able to provide feedback to Curry through telephone and the Internet, helping to shape the show's format on an ongoing basis.

Curry and SIRIUS are also working together to introduce some of SIRIUS' amazing talent to the PodShow.com world. "The combination of SIRIUS and PodShow.com creates the ultimate network," enthused Curry.
