Satellite Radio is one of the fastest growing entertainment industries. It was first developed in the late 1980s and early 1990s when XM and Sirius each paid $80 million for satellite radio licenses. While satellite radio offers benefits like no commercials and exclusive sports content, it also has drawbacks like significantly higher costs than traditional radio, with equipment, service, and maintenance potentially totaling over $1000 per year. In 2008, XM and Sirius merged to form a satellite radio monopoly while maintaining separate brands and programming.
