1950: The Turing Test

Alan Turing, an English mathematician and logician, advocated the theory that eventually computers could be created that would be capable of human thought. To cut through the long philosophical debate about exactly how to define thinking he proposed the "imitation game" (1950), now known as Turing test. His test consisted of a person asking questions via keyboard to both a person and an intelligent machine within a fixed time frame. After a series of tests the computers success at "thinking" could be measured by its probability of being misidentified as the human subject. Still today Turing's papers on the subject are widely acknowledged as the foundation of research in artificial intelligence.

The big "change" ...

With the invention of the printing press and - as a consequence - the distribution of information in masses (by then already mostly in the shape of propaganda), propaganda could change its methods. It could not only be produced but also reproduced and therefore spread widely.
The Protestant Reformation profited by this. The idea of translating the Bible into local languages was successful, because it got possible for many people to get a Bible, as books no longer were affordable only for the nobles and the Church.

Royalty and the Courts realized that prestige asked for propaganda and that it was impossible to reign over the people if their mood turned against the king. This gave the impetus for acting. Pamphlets were used for spreading royal messages; like the so-called "mazarinades" (Taylor, Munitions of the Mind, p. 122), written in a very simple language and spread periodically and in big numbers.
When - in 1896 - newspapers started being distributed in huge amounts, the access to propaganda and disinformation was opened extremely. Newspapers informed the mass - and disinformed them if it was considered as necessary (e.g. in war-times).
From that time on propaganda and manipulation were carried out for the most different political ideas and nearly without frontiers. Censorship - a part of disinformation - seems to have been the only barrier then. Sometimes even the source of a message kept hidden, which was part of the disinformation process. It is easier to spread ideas against somebody if the own name is kept hidden; and speaking out some kind of laudation that the own party is better without mentioning that it was oneself who spread it and therefore claim that it was someone else who praised the very idea.

George Boole

b. Nov. 2, 1815, Lincoln, Lincolnshire, England
d. Dec. 8, 1864, Ballintemple, County Cork, Ireland

English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits. One of the first Englishmen to write on logic, Boole pointed out the analogy between the algebraic symbols and those that can represent logical forms and syllogisms, showing how the symbols of quantity can be separated from those of operation. With Boole in 1847 and 1854 began the algebra of logic, or what is now called Boolean algebra. It is basically two-valued in that it involves a subdivision of objects into separate classes, each with a given property. Different classes can then be treated as to the presence or absence of the same property.

Framing

Framing is the practice of creating a frame or window within a web page where the content of a different web page can be display. Usually when a link is clicked on, the new web page is presented with the reminders of the originating page.

Roman smoke telegraph network, 150 A.D.

The Roman smoke signals network consisted of towers within visible range of each other and had a total length of about 4500 kilometers. It was used for military signaling.

For a similar telegraph network in ancient Greece see Aeneas Tacitus' optical communication system.
