With the introduction of the printing press into England in 1476 printing was made easier and faster and made copies less expensive. By the early 16th century two trades dominated the industry: independent printers and booksellers or stationers many of whom were vertically integrated as printers. At the time, the Crown was concerned about sedition and the Church about heresy. In 1557 by royal charter the Stationers' Company of London was created and exclusive rights granted. Approved printers were given the right to copy approved works. Accordingly the roots of copyright were censorship.
The Statute of Queen Ann, the first formal copyright law, was passed in 1710. Copyright was then conferred on the author of a work, but still the owner of copyright was nearly always the bookseller. Only in 1775 the House of Lords replaced the common law of printing rights in favor of the author.
In this tradition the underlying concept of copyright is monopoly, first granted to printers, then to booksellers and later to individual creators. Copyright is treated as a commodity to be bought and sold and inspired by a need to protect the public from the power of the artist.

With the rise of a global economic system a desire to establish agreements, which protect works not only within national borders, but also within a "Union" of countries or on an international level, has been expressed. As a consequence a variety of multilateral treaties have been negotiated and adopted by governments. Those shall simplify practice through international standardization and mutual recognition of rights and duties among nations.

Besides oral conversations and written language many other ways of information-transport are known: like the bush telegraph, drums, smoke signals etc. Those methods are not cryptography, still they need en- and decoding, which means that the history of language, the history of communication and the history of cryptography are closely connected to each other
The timeline gives an insight into the endless fight between enciphering and deciphering. The reasons for them can be found in public and private issues at the same time, though mostly connected to military maneuvers and/or political tasks.

Adbusters, well known as fighters against corporate disinformation, injustices in the global economy and "physical and mental pollution", timely for the WTO Conference purchased three billboards in downtown Seattle. Featuring an image with the text "System Error - Type 2000 (progress)", the billboards were meant to challenge "... the WTO's agenda of global corporate growth and expose what isn't reflected in the United State's GNP - human and environmental capital."
At the same time RTMark went on-line with its spoof WTO website http://gatt.org. Shortly after its release WTO Director-General Mike Moore accused RTMark of attempting to "undermine WTO transparency" by copying the WTO website's design and using "domain names such as `www.gatt.org` and page titles such as 'World Trade Organization / GATT Home Page' which make it difficult for visitors to realize that these are fake pages." http://gatt.org is not the first time that RTMark has used website imitation aiming at rendering an entity more transparent.

The largest media conglomerate in the world, Time Warner resulted from the merger of the publisher Time Inc. and the media company Turner Broadcasting Systems, Inc. in 1996. Time Inc. founded in 1922 primarily concentrated on magazines and books and in the 1950s moved into the broadcasting and entertainment industry, but in the 1970s announced that it was selling its broadcasting holdings and concentrating on cable television. In 1989 Time Inc. merged with Warner Communications Inc., which besides being a major motion-picture and television studio, was also one of the biggest U.S. music recordings producers and cable-television operators.
In January 2000 Time Warner merged with AOL (America Online) in a US$ 243.3 billion deal. Although AOL so far generated far less profit and turnover than Time Warner its quotation on the stock exchange was clearly higher, making Time Warner the junior partner (45 percent) in the new company. Through its merger with AOL, which is a major player in the online-business and owns several Internet-services like Compuserve, Netscape and Netcenter, the new media conglomerate could significantly enlarge its online presence and also complement its traditional media activities.

Artificial Intelligence is concerned with the simulation of human thinking and emotions in information technology. AI develops "intelligent systems" capable, for example, of learning and logical deduction. AI systems are used for creatively handling large amounts of data (as in data mining), as well as in natural speech processing and image recognition. AI is also used as to support

Educator who developed a system of printing and writing that is extensively used by the blind and that was named for him. Himself blind Braille became interested in a system of writing, exhibited at the school by Charles Barbier, in which a message coded in dots was embossed on cardboard. When he was 15, he worked out an adaptation, written with a simple instrument, that met the needs of the sightless. He later took this system, which consists of a six-dot code in various combinations, and adapted it to musical notation. He published treatises on his type system in 1829 and 1837.
Born in 1944, Giuliani became famous in the mid Eighties, as a typical Eighties figure: a censor of corruption and greed. In the Seventies he had switched his registration from Democratic to Republican, and served a stint in the Reagan Justice Department. In 1983 he became U.S. Attorney for the southern District of New York, and his career took off. He was aggressive, headline grabbing, none too scrupulous about the finer points of civil liberties, and often effective. He used the RICO Act against organized crime, and pioneered the use of asset forfeiture in prosecuting drug dealers. He also moved against political corruption in New York City, toppling the Democratic leaders of the Bronx and Queens.
DSL connections are high-speed data connections over copper wire telephone lines. As with cable connections, with DSL you can look up information on the Internet and make a phone call at the same time but you do not need to have a new or additional cable or line installed. One of the most prominent DSL services is ISDN (integrated services digital network, for more information click here (
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.

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.
