Digital Commercial Content Starting in the mid 1990s today most traditional media can also be found online. The overwhelming majority of bigger newspapers and periodicals, but also radio and TV stations now complement their classic media formats with digital programming. For the most part they transform existing analogue information in digital form, with some additional features. Especially the big media conglomerates, having realized the economic potential of the Internet, have started to get into the business of digital content. Not surprisingly their engagement in the virtual sphere has not brought much new concerning their programming. They offer entertainment, music, sports and some news channels. One of the reasons for this development might be, that the big commercial media companies are able to re-use already existing programming from their other ventures. Examples are Viacom's MTV Network, which now has a twin online or Time Warner's CNN, which on the Web is called CNN Interactive. Considering business economic factors this move suggests itself as hardly any further resources are needed and the already existing programming can be put in the Internet at little extra cost. Also, regarding the undeniable success of their traditional content in terms of revenue generation the digital reproduction of their classic programming concept seems to be an obvious step.

Satellites Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure. On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of very small aperture terminals (VSAT). Such networks are independent and make mobile access possible. In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
