If we look at history books we see the history of the winners, of men, of the rich and powerful ones. We read about a small part of the world's history - and very often we do not even realize this selective attitude. Those books disinform, telling us that they inform about what had happened in former times. Information turns into disinformation. Even being aware of this, we tend to live with it rather than change the system of selection.
Which means, we are accustomed to disinformation, as it is nothing new.
There is nothing like an exact history of disinformation, but the topic seems to have existed forever. With the help of disinformation, power and might can be prolonged, destroyed or gained. This is the secret of disinformation and its popularity.
Rumors were the first way of spreading news. Rumors tend to be interesting and they make people interesting: first of all the person who spreads the rumor and second the person who hears about it. Both of them think that they know something that others do not know yet - and this information advantage makes them special, at least for some moments, until the next rumor is spread or that one destroyed by some truth.
The "history" of disinformation is closely connected with the history of propaganda, though those two words do not mean the same thing. They are connected to each other and tend to influence each other in various ways.
What we tend to forget: everybody is disinforming sometimes, everybody is using propaganda. And persuasion is a common companion. The latter is less problematic though, as it uses less violence.

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.

Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments.
