Where does television come from?

Wherever you live, television pictures come to you from broadcasting stations located in various cities around the country. But they may get to you in several different ways.

Many programs are transmitted from a local television mast. They go to the mast from the broadcasting stations along cable or via radio links. Then from the mast, the programs come to the home as radio signals that are picked up by the aerial connected to the television set.

Homes that have cable television get their programs from a local television station through a cable connected to the set. It is also possible to receive television programs broadcast from special satellites in space.
