The framework allowed television to be transmitted across the continent, and indeed across the world from broadcast provider to broadcast provider, thus giving us the opportunity to see live action from the world.
During the 1960s and 1970s, computerization and miniaturization of control systems and the development of satellite receiver equipment meant that the possibility of mass produced hardware was realized and by 1980 satellite TV was being broadcast by Home Box Office, the Christian Broadcasting Network and other companies.
The increase in Satellite offerings generated sales of the "big dishes" for C-Band satellite, and prices began to fall seriously, opening up the mass market for . Growth incited the development of encryption software, which allowed broadcasters to secure payment for their services.
At this point, it was obvious that satellite TV was going a serious industry. The drawbacks were the size and complexity of the hardware and the needed to broadcast programs.
Research and development was funded by the industry, rather than being a spin-off from the space and defense industries, and dish size began to be . Computing was also making serious strides in development at this stage, and control systems began to be simplified. The user was made much simpler and intuitive.
Computerization also started to make an impact on and recording technique. The idea of digitization of the signal soon followed, making it easier to store, play back, and manipulate by computer techniques, all while smaller bandwidth.
Compression of the satellite signal became a of development and the MPEG (Moving Picture Experts Group) standards started to be defined. All of these changes laid the foundation for across technologies and manufacturers. Signal compression now allows the large amount of channels to be delivered by a relatively narrow beam, thus making it possible use a smaller satellite .
From 1992, when encryption techniques were sufficiently to allow the development of pay-per-view, the satellite TV industry really took off. Over the last 12 years more than 20 million satellite TV subscribers have encouraged providers to offer TV channels.
