Satellite Radios Reach Farther
Before the rapid production of television and MP3s, radios were the leading device for publicizing all kinds of media. Ask your grandparents, they'd know.
If you have tried using a radio in multiple cities, states, or even countries, you probably realize by now that the range of broadcasting you could receive on your radio is limited; you could only receive what the local radio towers feed you. For example, if you happen to be stuck somewhere in North Korea, you could only hear Korean propaganda through the radio. That would be a vexing idea if you were looking for some good ol' classical or rock music.
If you had what some call "the future of radio", you would not have trouble listening to broadcasts being broadcasted halfway across the world. This item is called the satellite radio, and with it, you could internationally access radio broadcasts.
