A satellite radio
is a special radio
that receives signals broadcast by satellite
. This allows the listener to follow a single channel no matter where they are because the signal's reach is not limited by station power and curvature of the Earth. Various stations in different genres are broadcast.
In the United States, two companies dominate satellite radio: XM Satellite Radio and Sirius Satellite Radio. A monthly fee is charged for the service.
Some critics of the serve have expressed worry that satellite radio will lead to a decline in the number and variety of local radio stations and programming and greater concentration of mass media in the hands of fewer companies, and a loss of jobs in the radio industry.
