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.
Despite the rapid growth of the Net, most computers linked to it are still located in the United States.

41st President of the United States. In 1954, George Bush co-founded and became the president of Zapata Offshore Company. By 1964, he became chairman of the Republican Party of Harris County. That same year, he ran for the U.S. Senate, but was defeated in the Democratic landslide. Bush had better luck in the election of 1966, when he became the first Republican ever to represent Houston in Texas. Presidents Nixon and Ford selected Bush for a series of high-profile appointments: Ambassador to the United Nations in 1971, Chairman of the Republican National Committee in 1973, envoy to China in 1974 and Director of Central Intelligence in 1976. When Jimmy Carter was elected President in 1976, he appointed a new Director and George Bush returned to private life. In 1980, Bush made his own run for the Presidency. George Bush sought the Presidency again in 1988, and won the Republican nomination over a large field of candidates. His election that November was a decisive one, though not the landslide he and Reagan had enjoyed in 1984.
