Positive Images
Certainly propaganda needs positive aspects as well: The art of circulating positive images even if the actual situation is unsuccessful, like in a war or before elections, when all opinion-polls are negative, is one which needs talent. Napoleon obviously possessed this talent. Another master of this was Adolf Hitler and the people working next to him. The way how he was portrayed as the father of the nation, the sensitive guide through that war - even at a moment when it should have been clear that there was nothing left to win for the Germans/Austrians in that war - is quite extraordinary and demonstrates a hard piece of work. But more than anything else it need the population's will to believe those propaganda-messages. And the Germans preferred to believe in Hitler than to look for another truth.

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.
