There is no national radio station in the US, but every large city has dozens of independent stations, which range from 24 hours day news to rock and classical music.
American radio broadcasts in two bands: FM and AM. Some stations are only talk radio — featuring interviews and discussions — while music radio stations broadcast one particular type of music: Top 40, hip-hop, country, etc. Radio broadcast companies have become increasingly consolidated in recent years. National Public Radio is the nation's primary public radio network, but most radio stations are commercial and profit-oriented.
A new form of radio that is gaining popularity is satellite radio. The two biggest subscriptions based radio services are Sirius Satellite Radio and XM Satellite Radio, which have recently both merged together to form Sirius XM Radio. Unlike terrestrial radio music channels are commercial free and other channels feature very minimal commercials
