World War I ...

With World War I an entire system of ideas how wars work collapsed. Suddenly it was no longer mostly soldiers who had to fight. War became an engagement of every day's life. Everybody got involved.
Propaganda therefore changed as well. The campaigns were no longer temporarily and recent but had to be planned for years. Who failed in organizing it or used the wrong keywords failed. Masters of modern propaganda became the British, whereas the Germans failed completely in the beginning.

Radio

Between the two World Wars the radio started becoming more and more important; as well in education (e.g. Walter Benjamin and Bertolt Brecht) as for propaganda.
By hearing unconsciously, without listening, while concentrating on something else, it is easy to spread ideas and emotions. This fact was taken advantage of.
The German Minister for Propaganda, Josef Goebbels, imagined the radio to be the most effective tool for propaganda. In fact the radio turned out to be a method to reach all generations at the same time, even the illiterates. By sending propaganda music and interrupting programs for the latest news, mostly good ones, the radio became popular.
Radio Moscow, which started working in 1922, tried to intervene in innerstate-affairs in Britain as well as in other countries. The radio was supposed to push ahead the idea of communism.

Comsat

The Communications Satellite Cooperation provides international communications solutions via the global, 17-satellite INTELSAT system and 4-satellite INMARSAT satellite systems. Calls are beamed up to the satellite and back down to Earth, where special gateway land earth stations re-route them through the appropriate local or international telephone network.

COMSAT operates Earth Stations in each part of the world to route calls efficiently within each ocean region. Earth Stations are located in Santa Paula, California; Southbury, Connecticut; Ankara, Turkey; and Kuantan, Malaysia.
