Sirius Satellite Radio

SIRIUS Satellite Radio is a paid service that provides thousands of radio channels to the subscriber, typically in cars as an alternative to traditional, advertiser-based A.M. and F.M. stations.

The music channels on SIRIUS are typically free of advertisements, but the talk shows can have advertisers.

Rental cars often provide SIRIUS for free as a way of introducing drivers to the service. New cars are also often equipped to provide SIRIUS for a limited time for free.
