Galaxy 1 was the first in a line of Galaxy communications satellites launched by Hughes Communications in 1983.
It helped fill a hole in satellite broadcasting bandwidth created by the loss of RCA's Satcom 3 in 1979. Unlike satellite owners RCA and Western Union, Hughes did not lease time on their transponders in the fashion of a common carrier, but instead sold transponders outright to content providers. This created a stable lineup of content attractive enough for cable providers to dedicate Earth station receivers to it full-time.
Among the services on Galaxy 1 by mid-1984: HBO, Cinemax, The Movie Channel, Showtime, The Disney Channel, TBS, CNN, ESPN, and The Nashville Network.
