New opportunities for online advertisers arise with the possibility of one-to-one Web applications. Software agents for example promise to "register, recognize and manage end-user profiles; create personalized communities on-line; deliver personalized content to end-users and serve highly targeted advertisements". The probably ultimate tool for advertisers. Although not yet widely used, companies like

Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early
Therefore
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

At the beginning of the story of today's global data networks is the story of the development of
In 1955 President Eisenhower announced the USA's intention to launch a satellite. But it in the end it was the Soviet Union, which launched the first satellite in 1957: Sputnik I. After Sputnik's launch it became evident that the Cold War was also a race for leadership in the application of state-of-the-art technology to defense. As the US Department of Defense encouraged the formation of high-tech companies, it laid the ground to Silicon Valley, the hot spot of the world's computer industry.
The same year as the USA launched their first satellite - Explorer I - data was transmitted over regular phone circuits for the first time, thus laying the ground for today's global data networks.
Today's satellites may record weather data, scan the planet with powerful cameras, offer global positioning and monitoring services, and relay high-speed data transmissions. Yet up to now, most satellites are designed for military purposes such as reconnaissance.

ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. An experimental network it mainly served the purpose of testing the feasibility of
In 1969 ARPANET went online and linked the first two computers, one located at the University of California, Los Angeles, the other at the Stanford Research Institute.
Yet ARPAnet did not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972.
Before it was decommissioned in 1990,
In the USA it was already in 1994 that commercial users outnumbered military and academic users.

An international organization designed to supervise and liberalize world trade. The WTO (World Trade Organization) is the successor to the General Agreement on Tariffs and Trade (GATT), which was created in 1947 and liberalized the world's trade over the next five decades. The WTO came into being on Jan. 1, 1995, with 104 countries as its founding members. The WTO is charged with policing member countries' adherence to all prior GATT agreements, including those of the last major GATT trade conference, the Uruguay Round (1986-94), at whose conclusion GATT had formally gone out of existence. The WTO is also responsible for negotiating and implementing new trade agreements. The WTO is governed by a Ministerial Conference, which meets every two years; a General Council, which implements the conference's policy decisions and is responsible for day-to-day administration; and a director-general, who is appointed by the Ministerial Conference. The WTO's headquarters are in Geneva, Switzerland.
One of the world's largest corporate entities in sales, consisting of companies in more than 100 countries, whose shares are owned by NV Koninklijke Nederlandsche Petroleum Maatschappij (Royal Dutch Petroleum Company Ltd.) of The Hague and by the "Shell" Transport and Trading Company, PLC, of London. Below these two parent companies are two holding companies, Shell Petroleum NV and the Shell Petroleum Company Limited, whose shares are owned 60 percent by Royal Dutch and 40 percent by "Shell" Transport and Trading. The holding companies, in turn, hold shares in and administer the subsidiary service companies and operating companies around the world, which engage in oil, petrochemical, and associated industries, from research and exploration to production and marketing. Several companies also deal in metals, nuclear energy, solar energy, coal, and consumer products.

French mathematician, physicist, religious philosopher, and master of prose. He laid the foundation for the modern theory of probabilities, formulated what came to be known as Pascal's law of pressure, and propagated a religious doctrine that taught the experience of God through the heart rather than through reason. The establishment of his principle of intuitionism had an impact on such later philosophers as Jean-Jacques Rousseau and Henri Bergson and also on the Existentialists.
