The 19th Century: First Programmable Computing Devices

Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early calculators like the abacus worked with a system of sliding beads arranged on a rack and the centerpiece of Leibniz's multiplier was a stepped-drum gear design.

Therefore Charles Babbage's proposal of the Difference Engine (1822), which would have (it was never completed) a stored program and should perform calculations and print the results automatically, was a major breakthrough, as it for the first time suggested the automation of computers. The construction of the Difference Engine, which should perform differential equations, was inspired by Babbage's idea to apply the ability of machines to the needs of mathematics. Machines, he noted, were best at performing tasks repeatedly without mistakes, while mathematics often required the simple repetition of steps.

After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer.

The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed.

Of extraordinary importance for the evolution of digital computers and artificial intelligence have furthermore been the contributions of the English mathematician and logician George Boole. In his postulates concerning the Laws of Thought (1854) he started to theorize about the true/false nature of binary numbers. His principles make up what today is known as Boolean algebra, the collection of logic concerning AND, OR, NOT operands, on which computer switching theory and procedures are grounded. Boole also assumed that the human mind works according to these laws, it performs logical operations that could be reasoned. Ninety years later Boole's principles were applied to circuits, the blueprint for electronic computers, by Claude Shannon.

Introduction: The Substitution of Human Faculties with Technology: Artificial Intelligence and Expert Systems

Research in artificial intelligence, starting in the 1960s, yet formulated a new goal: the automation of thought processes with intelligent machines. Although first attempts to develop "thinking" machines had only little success as the aimed at solving very general problems, the invention of expert systems marked a breakthrough. Albeit the application of those semi-intelligent systems is (still) restricted to quite narrow domains of performance, such as taxation and medical image interpretation, they are able to mimic the knowledge and reasoning capabilities of an expert in a particular discipline. While the development of intelligent machines, which are able to reason, to generalize and to learn from past experience is not likely to become reality in the very near future, research in artificial intelligence progresses quickly and sooner or later the substitution of men's unique faculties will come true.

General Electric

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.

Intelsat

Intelsat, the world's biggest communication satellite services provider, is still mainly owned by governments, but will be privatised during 2001, like Eutelsat. A measure already discussed 1996 at an OECD competition policy roundtable in 1996. Signatory of the Intelsat treaty for the United States of America is Comsat, a private company listed on the New York Stock Exchange. Additionally Comsat is one of the United Kingdom's signatories. Aggregated, Comsat owns about 20,5% of Intelsat already and is Intelsat's biggest shareholder. In September 1998 Comsat agreed to merge with Lockheed Martin. After the merger, Lockheed Martin will hold at least 49% of Comsat share capital.
