1713
First typewriter patent filed

In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing. Still it was not before 1808 that the first typewriter proven to have worked was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. The commercial production of typewriters began in 1873.

For a brief history of typewriters see Richard Polt, The Classic Typewriter Page, http://xavier.xu.edu/~polt/typewriters.html

1727
First photocopies

Searching for the Balduinist fluorescenting phosphor (Balduinischer Leuchtphosphor), an artificial fluorescent, Johann Heinrich Schulze realized the first photocopies, but did not put them into practical use.

The first optical photocopier was not patented before 1843, when William Henry Fox Talbot got granted a patent for his magnifying apparatus.

In 1847 Frederick Collier Bakewell developed a procedure for telecopying, a forerunner of the fax machine. Yet it was not before 1902 that images could be transmitted. Almost 200 years after Schulze's discovery, for the first time photo telegraphy was offered as a telecommunication service in Germany in 1922.

1794
Fixed optical network between Paris and Lille

Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores.
Because the communication system was designed for practical military use, the transmitted messages were encoded. The messages were kept such a secret that even those who transmit them from tower to tower did not capture their meaning; they transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best.

Forerunners of Chappe's optical network are the Roman smoke signals network and Aeneas Tacitus' optical communication system.

For more information on early communication networks see Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks.

So what does cryptography mean?

cryptography:
It is the study of encryption, the art/science to create and use codes and/or ciphers with the purpose of enciphering as well as deciphering.
After a relatively vivid but slow development of cryptography for nearly 4.000 years the inventions of the telegraph, radio and computer had a high impact on the velocity of further inventions concerning encryption.
Most of the time economic, political or military reasons lie behind the necessity of encryption. As visible from the timetable cryptography it is also done for private and individual interests. An extraordinary example for this is the Braille Code, developed as a possibility for blind people to read and write.
A lot of very interesting and intelligent websites about cryptography can be found in the Internet.Some websites offering links to various cryptography-websites are:

1400 - 1500 A.D.

1455
Johannes Gutenberg publishes the Bible as the first book in Europe by means of a movable metal font.

Gutenberg's printing press was an innovative aggregation of inventions known for centuries before Gutenberg: the olive oil press, oil-based ink, block-print technology, and movable types allowed the mass production of the movable type used to reproduce a page of text and enormously increased the production rate. During the Middle Ages it took monks at least a year to make a handwritten copy of a book. Gutenberg could print about 300 sheets per day. Because parchment was too costly for mass production - for the production of one copy of a medieval book often a whole flock of sheep was used - it was substituted by cheap paper made from recycled clothing of the massive number of deads caused by the Great Plague.

Within forty-five years, in 1500, ten million copies were available for a few hundred thousand literate people. Because individuals could examine a range of opinions now, the printed Bible - especially after having been translated into German by Martin Luther - and increasing literacy added to the subversion of clerical authorities. The interest in books grew with the rise of vernacular, non-Latin literary texts, beginning with Dante's Divine Comedy, the first literary text written in Italian.

Among others the improvement of the distribution and production of books as well as increased literacy made the development of print mass media possible.

Michael Giesecke (Sinnenwandel Sprachwandel Kulturwandel. Studien zur Vorgeschichte der Informationsgesellschaft, Frankfurt am Main: Suhrkamp, 1992) has shown that due to a division of labor among authors, printers and typesetters Gutenberg's invention increasingly led to a standardization of - written and unwritten - language in form of orthography, grammar and signs. To communicate one's ideas became linked to the use of a code, and reading became a kind of rite of passage, an important step towards independency in a human's life.

With the growing linkage of knowledge to reading and learning, the history of knowledge becomes the history of reading, of reading dependent on chance and circumstance.

History: Communist Tradition

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.

Governmental Influence

Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA.
Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data.

See the U.S. discussion about the Clipper Chip some years ago:
http://www.epic.org/crypto/clipper/
http://www.cdt.org/crypto/admin/041693whpress.txt

While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now.

First European medieval university is established in Bologna.

The first of the great medieval universities was established in Bologna. At the beginning universities predominantly offered a kind of do-it-yourself publishing service.

Books still had to be copied by hand and were so rare that a copy of a widely desired book qualified for being invited to a university. Holding a lecture equaled to reading a book aloud, like a priest read from the Bible during services. Attending a lecture equaled to copy a lecture word by word, so that you had your own copy of a book, thus enabling you to hold a lecture, too.

Extract of Disney’s Content Production and Distribution Holdings

Although the traditional media companies first steps into the digital sphere were fairly clumsy, they have quickly learned from their mistakes and continued to enlarge their Internet presence. Time Warner now for instance operates about 130 Web-Sites (http://www.timewarner.com/corp/about/pubarchive/websites.html). Anyhow the stronger online-engagement of the big media conglomerates by 1998 has led to the establishment of a new pattern: "More than three-quarters of the 31 most visited news and entertainment websites were affiliated with large media firms, and most of the rest were connected to outfits like AOL and Microsoft." (Broadcasting and Cable, 6/22/98).

During the last years many of the smaller players in the field of digital media have been driven out of competition by the huge media conglomerates. This mainly is a result of the advantages that the commercial media giants have over their less powerful counterparts:

    As engagement in online activities mostly does not lead to quick profits, investors must be able to take losses, which only powerful companies are able to.



    Traditional media outlets usually have huge stocks of digital programming, which they can easily plug into the Internet at little extra cost.



    To generate audience, the big media conglomerates constantly promote their Websites and other digital media products on their traditional media holdings.



    As possessors of the hottest "brands" commercial media companies often get premier locations from browser software makers, Internet service providers, search engines and portals.



    Having the financial resources at their disposition the big media firms are aggressive investors in start-up Internet media companies.



Commercial media companies have close and long ties to advertisers, which enables them to seize most of these revenues.

Charles Babbage

b. December 26, 1791, London, England
d. October 18, 1871, London, England

English mathematician and inventor who is credited with having conceived the first automatic digital computer. The idea of mechanically calculating mathematical tables first came to Babbage in 1812 or 1813. Later he made a small calculator that could perform certain mathematical computations to eight decimals. During the mid-1830s Babbage developed plans for the so-called analytical engine, the forerunner of the modern digital computer. In this device he envisioned the capability of performing any arithmetical operation on the basis of instructions from punched cards, a memory unit in which to store numbers, sequential control, and most of the other basic elements of the present-day computer.

Intellectual property

Intellectual property, very generally, relates to the output that result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) industrial property (inventions, marks, industrial designs, unfair competition and geographical indications), and 2) copyright. The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products.

World Wide Web (WWW)

Probably the most significant Internet service, the World Wide Web is not the essence of the Internet, but a subset of it. It is constituted by documents that are linked together in a way you can switch from one document to another by simply clicking on the link connecting these documents. This is made possible by the Hypertext Mark-up Language (HTML), the authoring language used in creating World Wide Web-based documents. These so-called hypertexts can combine text documents, graphics, videos, sounds, and Java applets, so making multimedia content possible.

Especially on the World Wide Web, documents are often retrieved by entering keywords into so-called search engines, sets of programs that fetch documents from as many servers as possible and index the stored information. (For regularly updated lists of the 100 most popular words that people are entering into search engines, click here). No search engine can retrieve all information on the whole World Wide Web; every search engine covers just a small part of it.

Among other things that is the reason why the World Wide Web is not simply a very huge database, as is sometimes said, because it lacks consistency. There is virtually almost infinite storage capacity on the Internet, that is true, a capacity, which might become an almost everlasting too, a prospect, which is sometimes consoling, but threatening too.

According to the Internet domain survey of the Internet Software Consortium the number of Internet host computers is growing rapidly. In October 1969 the first two computers were connected; this number grows to 376.000 in January 1991 and 72,398.092 in January 2000.

Gottfried Wilhelm von Leibniz

b. July 1, 1646, Leipzig
d. November 14, 1716, Hannover, Hanover

German philosopher, mathematician, and political adviser, important both as a metaphysician and as a logician and distinguished also for his independent invention of the differential and integral calculus. 1661, he entered the University of Leipzig as a law student; there he came into contact with the thought of men who had revolutionized science and philosophy--men such as Galileo, Francis Bacon, Thomas Hobbes, and René Descartes. In 1666 he wrote De Arte Combinatoria ("On the Art of Combination"), in which he formulated a model that is the theoretical ancestor of some modern computers.

RSA

The best known of the two-key cryptosystems developed in the mid-1980s is the Rivest-Shamir-Adleman (RSA) cryptoalgorithm, which was first published in April, 1977. Since that time, the algorithm has been employed in the most widely-used Internet electronic communications encryption program, Pretty Good Privacy (PGP). It is also employed in both the Netscape Navigator and Microsoft Explorer web browsing programs in their implementations of the Secure Sockets Layer (SSL), and by Mastercard and VISA in the Secure Electronic Transactions (SET) protocol for credit card transactions.
