Radios transmit waves across the world to satellites.
The key aspects of this system include:
- radio waves
- display systems
They go through the process by starting at whatever the radio source is. They get taken in by the satellite dish, then are transferred from cables to a receiver, which moves to a computer and then is seen in the output we know of as video or sound.
We control this ourselves a bit by choosing to intake certain videos or sounds, which then makes more satellites needed if there is a larger demand so that it can reach more people. Additionally we are send our own signals out, so we can also become the radio source if we wanted to. This has allowed us to be collaborative and share things with other people.
