Satellite pact to beam signal to 10 million homes.

Sirius Satellite Radio has forged an agreement with Echostar's Dish satellite television network that will beam the radio service into more than 9.7 million homes in the United States.

The deal, which goes into effect today, will provide subscribers to the Dish network with access to all of Sirius' 64 music channels, spanning numerous genres. There is no extra charge for Dish subscribers.

Sirius' full range of offerings comprises 110 channels, including syndicated and original talk-radio programming.

The Sirius channels will become the Dish network's only music offerings, and will give Sirius a far wider market penetration than it has previously enjoyed. Sirius' subscriber base numbers around 350,000, according to figures released by the company in April.
