First of all,I want to share the history of communication satellite because most of us does not know how it works and who is develop this satellite communication.If i ask some question about this they do not know about it because some school does not relate this in life.
In 1962, the world's first active communications satellite, Telstar 1, was launched. This satellite was built by Telesat's predecessors at AT&T and Bell Laboratories. During seven months in operation, Telstar 1 dazzled the world with live images of sports, entertainment and news. It was a simple single-transponder low-earth-orbit (LEO) satellite, but its technology of receiving radio signals from the ground, and then amplifying and re transmitting them over a large portion of the earth's surface, set the standard for all communications satellites that followed.

During the 1960s and 1970s, advances in satellite performance came quickly and a global industry began to develop. Satellites were mainly used at first for international and long-haul telephone traffic and distribution of select television programming, both internationally and domestically. In 1973 the Canadian Broadcasting Corporation began distributing its video programming to Canadian customers using Telesat’s Anik A satellite. Then in 1975 HBO began distributing its video programming to US customers by satellite. The commercial and technical success of these ventures led to a greater use and acceptance of satellite broadcasting. By the 1990s, satellite communications would be the primary means of distributing TV programs around the world.
