It was in 1962 that the very first television signal was up linked from Europe on to the Telstra satellite and beamed over North America. Anik1 was the first domestic North American satellite launched in 1973 in Canada.
Well, without going technical, it will interest you to note that the television signals you receive from communications satellites are really first sent up from ground stations via very big (9 - 12 meters) dishes to an orbiting satellite that in turn beams the signals down to earth and on to your receiver's parabolic dish's focal point and a LNB or low noise blocker component converts ands send the signals to your decoder box where the final conversion is done to the signals so that it becomes the sound and pictures you watch.

There are also different brands of mobile none parabolic dish receivers for use in vehicles and other mobile platforms. In this case satellite television signals are received with a satellite antenna and directed through a satellite decoder box and an oscillator converts it to L-band range of frequencies that an on-board electronics finally converts to the standard frequency usable by normal television sets.
Television Receive Only or TVRO is the forerunner of satellite television viewing at home. The very big dish size, about 3 - 6 feet, required to run C-Band frequencies of about four G Hertz meant that not most people could own it due to the very exorbitant cost of installing one, and the space for installation.
One other hassle with TVRO is that the big dish has to be moveable to keep track of more satellite, because C-Band satellites carry less channels than KU-band satellites. This dish movement, however makes it possible to receive free channels and feeds or even unedited C-Band news material being sent to headquarters by field correspondence or a news crew, they are usually not scrambled.
