Timeline of Communication Systems: Introduction

The timeline of communication systems presents a chronological overview of the most important events in the history of communication systems from the 4th millennium B.C. to the present.

It shows that from the very beginning - the first Sumerian pictographs on clay tablets to today's state-of-the-art technologies - broadband communication via fiber-optic cables and satellites - the amount of information collected, processed and stored, the capabilities to do so, as well as the capable speed of information transmission exponentially accelerate.

The 17th Century: The Invention of the First "Computers"

The devices often considered the first "computers" in our understanding were rather calculators than the sophisticated combination of hard- and software we call computers today.

In 1642 Blaise Pascal, the son of a French tax collector, developed a device to perform additions. His numerical wheel calculator was a brass rectangular box and used eight movable dials to add sums up to eight figures long. Designed to help his father with his duties, the big disadvantage of the Pascaline was its limitation to addition.

Gottfried Wilhelm von Leibniz, a German mathematician and philosopher, in 1694 improved the Pascaline by creating a machine that could also multiply. As its predecessor Leibniz's mechanical multiplier likewise worked by a system of gears and dials. Leibniz also formulated a model that may be considered the theoretical ancestor of some modern computers. In De Arte Combinatoria (1666) Leibniz argued that all reasoning, all discover, verbal or not, is reducible to an ordered combination of elements, such as numbers, words, colors, or sounds.

Further improvements in the field of early computing devices were made by Charles Xavier Thomas de Colmar, a Frenchmen. His arithometer could not only add and multiply, but perform the four basic arithmetic functions and was widely used up until the First World War.

Advertisers and Marketers Perspective

With the rapid growth of the Internet and its audience advertisers now have a new medium at their disposal. The placement of the first banner ads in 1994 marks the birth of Internet advertising. Although the advertising industry at first hesitated to adopt the new medium, two facts brushed away their doubts:

Migrating Television Audiences: The increased use of the Internet led people to redistribute their time budget. Whereas some cut down on eating and sleeping, more than a third reduced watching television and instead uses the WWW.

Interesting Internet Demographics: While methodologies and approaches of research organizations studying the demographic composition of the Internet vary, the findings are relatively consistent: Internet users are young, well educated and earn high incomes.

Considering those findings, the Internet in the first place seems to become inevitable to be included in media planning, as part of the audience shifts from TV to the WWW, and secondly, because demographics of the Internet user population are irresistible for marketers.

biotechnology summary

The fusion of flesh and machine is trend which, although inscribed in the history of modern technology from its beginnings, has reached a unprecedented momentum in recent years as a result of crucial advances in information technology, biology, and the development of global networks. Consequently, doubts are emerging concerning the viability of a distinct and definable human nature. Historical and social theories and concepts are being unhinged by the spread hybrids and by new forms of artificial life which are likely to trigger social changes escaping the grip of calculation. Attempts to defend an essential human nature against technical hybridisation, rather than strengthening the human subject, may have further blurred the question of historical subjectivity. Large amounts of money are invested into research and development of artifical biology, making some of the predictions of AI and robotics experts about radical and far reaching changes a matter of time.

water-clocks

The water-clocks are an early long-distance-communication-system. Every communicating party had exactly the same jar, with a same-size-hole that was closed and the same amount of water in it. In the jar was a stick with different messages written on. When one party wanted to tell something to the other it made a fire-sign. When the other answered, both of them opened the hole at the same time. And with the help of another fire-sign closed it again at the same time, too. In the end the water covered the stick until the point of the wanted message.
