Terrestrial television is a term which refers to modes of television broadcasting which do not involve satellite transmission.
[1]. The term is uncommon in the United States, and more common in Europe.Terrestrial television broadcasting dates back to the very beginnings of
television as a medium itself with the first long-distance public television broadcast from
Washington, D.C., on
April 7,
1927. Aside from transmission by high-flying planes moving in a loop using a system developed by
Westinghouse called
Stratovision, there was virtually no other method of
television delivery until the
1950s with the beginnings of
cable television, or community antenna television (CATV). The first non-terrestrial method of delivering television signals that in no way depended on a signal originating from a traditional terrestrial source began with the use of
communications satellites during the
1960s and
1970s.
