Digital technologies are used to combine previously separated communication and media systems such as telephony, audiovisual technologies and computing to new services and technologies, thus forming extensions of existing communication systems and resulting in fundamentally new communication systems. This is what is meant by today's new buzzwords "multimedia" and "convergence".
Classical dichotomies as the one of computing and telephony and traditional categorizations no longer apply, because these new services no longer fit traditional categories.
Convergence and Regulatory Institutions
Digital technology permits the integration of telecommunications with computing and audiovisual technologies. New services that extend existing communication systems emerge. The convergence of communication and media systems corresponds to a convergence of corporations. Recently,

900 B.C.
A postal service is used for governmental purposes in China.
500 B.C.
In ancient Greece trumpets, drums, shouting, beacon, fires, smoke signals, and mirrors are used for message transmission.
4th century B.C.
Aeneas Tacitus, a Greek military scientist and cryptographer, invented an optical communication system that combines water and beacon telegraphy. Torches indicated the beginnings and the ends of a message transmission while water jars were used to transmit the messages. These jars had a plugged standard-size hole drilled on the bottom side and were filled with water. As those who sent and those who received the message unplugged the jars simultaneously, the water drained out. Because the transmitted messages corresponded to water levels, the sender indicated by a torch signal that the appropriate water level had been reached. The methods disadvantage was that the possible messages were restricted to a given code, but as the system was mainly used for military purposes, this was offset by the advantage that it was almost impossible for outsiders to understand the messages unless they possessed the codebook.
With communication separated from transportation, the distant became near. Tacitus' telegraph system was very fast and not excelled until

Wax tablets are used as writing material in Mesopotamia, ancient Greece, and Etruria.
2nd century B.C.
In China paper is invented.
1st century B.C.
The use of codices instead of scrolls - basically the hardcover book as we know it today - is an essential event in European history. To quote accurately by page number, to browse through pages and to skip chapters - things that were impossible when reading scrolls - becomes possible.
In the computer age we are witnesses to a kind of revival of the scrolls as we scroll up and down a document. The introduction of hypertext possibly marks the beginning of a similar change as has taken place with the substitution of scrolls with codices.

Since the invention of appropriate means and technologies, communication no longer requires face-to-face meetings.
From writing and reading to using computers, expanding and exhausting one's possibilities to communicate relies more and more on the application of skills we have to learn. With the increasing importance of communication technologies, learning to apply them properly becomes a kind of rite of passage.
A Small World
From the very beginning - the first Sumerian pictographs on clay tablets - to today's state of the art technologies - broadband communication via
Since the invention of the electrical telegraph, but especially with today's growing digital communication networks, every location on earth seems to be close, however distant it may be, and also time no longer remains a significant dimension.
Threatened Cultural Memory
More and more information is transmitted and produced faster and faster, but the shelf life of information becomes more and more fragile. For more than 4500 years Sumerian pictographs written on clay tablets remained intact, but newspapers and books, printed some decades ago, crumble into pieces; film reels, video tapes and cassettes corrode. Digitalization of information is not a cure; on the contrary it even intensifies the danger of destroying cultural heritage. Data increasingly requires specific software and hardware, but to regularly convert all available digitized information is an unexecutable task.
Compared to the longevity of pictographs on clay tablets, digitized information is produced for instant one-time use. The increasing production and processing of information causes a problem hitherto unknown: the loss of our cultural memory.

1713
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.

1727
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
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

The ICPC aims at reducing the number of incidents of damages to submarine telecommunications cables by hazards.
The Committee also serves as a forum for the exchange of technical and legal information pertaining to submarine cable protection methods and programs and funds projects and programs, which are beneficial for the protection of submarine cables.
Membership is restricted to authorities (governmental administrations or commercial companies) owning or operating submarine telecommunications cables. As of May 1999, 67 members representing 38 nations were members.

Agostino Ramelli designed a "reading wheel" which allowed browsing through a large number of documents without moving from one spot.
Presenting a large number of books, a small library, laid open on lecterns on a kind of ferry-wheel, allowing us to skip chapters and to browse through pages by turning the wheel to bring lectern after lectern before our eyes, thus linking ideas and texts together, Ramelli's reading wheel reminds of today's browsing software used to navigate the
Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets are used for administrative purposes. As an instrument for the administrative bodies of early empires, who began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to a few. Being more or less separated tasks, writing and calculating converge in today's computers.
Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China.
