The ancient Greek |
 |
Disinformation was seen as an appropriate tool of politics and rhetoric in ancient Greece. Most of all persuasion was used, which then was considered a type of art.
Religion was (and in many ways still is) the best disinformer or manipulator; prophecies were constructed to manipulate the population. The important thing was to use emotions and more than anything else fear as a tool for manipulation. If the oracle of Delphi said a war was to fight and would be won, then the Greek population - because of religious motives - was prepared to fight that war.
Propaganda was not only used in wars but also in daily life to bring people together and create a nation.
But poets, playwrights and other artists were manipulating as well. Their pieces of literature and plays were full of political messages with different ideologies behind. In the way how theatre at that time was part of life, it can be understood easily that those messages had not only entertainment's character but also a lot of political and social influence.
A different and very famous part of disinformation in ancient Greek history was the story of  Themistocles, who won the battle of Salamis against the Persians.

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.
