late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly
1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts
1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939
1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of
1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett
- at the same time the British develop the Typex machine, similar to the German Enigma machine
1943 Colossus, a code breaking computer is put into action at Bletchley Park
1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type
1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems

In the space of flows constituted by today's global data networks the space of places is transcended. Visualizations of these global data flows show arches bridging seas and continents, thereby linking the world's centres of research and development, economics and politics. In the global "Network Society" (Manuel Castells) the traditional centres of power and domination are not discarded, in the opposite, they are strengthened and reinforced by the use of information and communication technologies. Political, economical and symbolical power becomes increasingly linked to the use of modern information and communication technologies. The most sensitive and advanced centres of information and communication technologies are the stock markets. Excluded from the network constituted by modern information and communication technologies, large parts of Africa, Asia and South America, but also the poor of industrialized countries, are ranking increasingly marginal to the world economy.
Cities are centres of communications, trade and power. The higher the percentage of urban population, the more it is likely that the telecommunications infrastructure is generally good to excellent. This goes hand in hand with lower telecommunications costs. Those parts of the world with the poorest infrastructure are also the world's poorhouse. In Bangladesh for most parts of the population a personal computer is as expensive as a limousine in European one-month's salary in Europe, they have to pay eight annual salaries. Therefore telecommunications infrastructure is concentrated on the highly industrialized world: Most telephone mainlines, mobile telephones, computers, Internet accounts and Internet hosts (computers connected to the global data networks) can be found here. The same applies to media: the daily circulation of newspapers and the use of TV sets and radios. - Telecommunication and media services affordable to most parts of the population are mostly restricted to industrialized countries.
This situation will not change in the foreseeable future: Most expenditure for telecommunications infrastructure will be restricted to the richest countries in the world. In 1998, the world's richest countries consumed 75% of all cables and wires.

Cartoons' technique is simplicity.
Images are easier to remember than texts.
Frequently they show jokes about politicians, friendly or against the person shown. In the first decades of this century, cartoons were also used for propaganda against artists; remember the famous cartoons of
As a tool in politics it had fatal consequences by determining stereotypes, which never again could be erased even if detected as pure disinformation. Most famous got the cartoons about Jews, which were not only distributed by Germans and Austrians but all over Europe; and already in the tens and twenties of our century. Most horrifying is the fact that many of those old, fascist and racist cartoons are coming back now, in slightly different design only.

Following the communist revolutions of the 20th century all "means of production" became the property of the state as representative of "the masses". Private property ceased to exist. While moral rights of the creator were recognized and economic rights acknowledged with a one-time cash award, all subsequent rights reverted to the state.
With the transformation of many communist countries to a market system most of them have now introduced laws establishing markets in intellectual property rights. Still the high rate of piracy reflects a certain lack of legal tradition.

GE is a major American corporation and one of the largest and most diversified corporations in the world. Its products include electrical and electronic equipment, plastics, aircraft engines, medical imaging equipment, and financial services. The company was incorporated in 1892, and in 1986 GE purchased the RCA Corporation including the RCA-owned television network, the National Broadcasting Company, Inc. In 1987, however, GE sold RCA's consumer electronics division to Thomson SA, a state-owned French firm, and purchased Thomson's medical technology division. In 1989 GE agreed to combine its European business interests in appliances, medical systems, electrical distribution, and power systems with the unrelated British corporation General Electric Company. Headquarters are in Fairfield, Conn., U.S.
David Kahn can be considered one of the most important historians on cryptography. His book The Codebreakers. The comprehensive history of secret Communication from Ancient Times to the Internet, written in 1996 is supposed to be the most important work on the history of cryptography.
Founded by Bill Gates and Paul Allen and headquartered in Redmond, USA, Microsoft Corporation is today's world-leading developer of personal-computer software systems and applications. As MS-DOS, the first operating system released by Microsoft, before, Windows, its successor, has become the de-facto standard operating system for personal computer. According to critics and following a recent court ruling this is due to unfair competition.
