Satellites send television signals directly to homes, but they also are the backbone of cable and network TV. These satellites send signals from a central station that generates programming to smaller stations that send the signals locally via cables or the airwaves.13 Feb 2014

What do satellites actually do?
Thousands of artificial, or man-made, satellites orbit Earth - some are used to track weather, some are used to take pictures of space, other planets and galaxies. Some satellites are used for communications: beaming TV signals and phone calls around the world.
How do satellites help humans?
Satellites in space allow us to share information across the whole world. The signals used by TV and mobile phones use a type of light called radio waves. Radio waves can travel long distances but only in a straight line. This means they can't go around the curve of the Earth.
