Analog systems have been predominant in television for the past 50 years now. However, it is apparent that digitalization will be the shape of things to come. For several years now, satellite television and cable have been in digital formats, usually MPEG and DVB-S.  digital satellite tv  has been the norm for satellite television service since the 80s and it is apparent that there is no going back. As time goes on we will likely see less and less of the analog television that we are now used to and technology used in digital satellite tv will become the standard even for normal broadcasts, when the price of technology goes down.
