Satellites fly high in the sky, so they can see large areas of Earth at one time. Satellites also have a clear view of space. That's because they fly above Earth's clouds and air.
Before satellites, TV signals didn't go very far. TV signals only travel in straight lines. So they would go off into space instead of following Earth's curve. Sometimes they would be blocked by mountains or tall buildings.
Phone calls to faraway places were also a problem. It costs a lot and it is hard to set up telephone wires over long distances or underwater.
With satellites, TV signals and phone calls can be sent up to a satellite. The satellite can then send them back down to different spots on Earth.

A further complication is that you have provided no time limit. It is almost certain that a satellite will hit someone in the US over the next few billion years - although the country may not be called the US then!
