Sirius Satellite Radio, the satellite radio broadcaster, today began the first phase of its national service rollout in four metropolitan markets, Denver, Houston, Phoenix and Jackson, Mississippi. To commemorate the start of its satellite radio service, Sirius broadcast inaugural programming and treated Jackson to a special live concert featuring Randy Travis and a host of country artists.

“This is an important day in Sirius’ history and we are thrilled to bring our premier satellite radio service to listeners in Denver, Houston, Phoenix and Jackson,” said Joseph P. Clayton, Sirius’ President and CEO. “This will be a big year for Sirius as we roll out our service nationwide, and embark on our mission to bring the Sirius experience directly to listeners everywhere. We believe that once people visit our ‘Rhythm of the Road Tour’ in their hometown and listen to music the way it was meant to be heard, completely commercial free, people will be lining up to get Sirius,” Mr. Clayton said.

Sirius is in competition with already US nation-wide XM satellite radio.

XM channels originate from XM’s broadcast centre in Washington and are transmitted across the US via two satellites. It is commercial free and users pay a monthly subscription fee. It was launched in September of last year.
