1957: Sputnik has launched ARPA

1957 - October 4th - the USSR launches Sputnik, the first artificial earth satellite.

1958 - February 7th - In response to the launch of Sputnik, the US Department of Defense issues directive 5105.15 establishing the Advanced Research Projects Agency (ARPA).

The organization united some of America's most brilliant people, who developed the United States' first successful satellite in 18 months. Several years later ARPA began to focus on computer networking and communications technology.

In 1962, Dr. J.C.R. Licklider was chosen to head ARPA's research in improving the military's use of computer technology. Licklider was a visionary who sought to make the government's use of computers more interactive. To quickly expand technology, Licklider saw the need to move ARPA's contracts from the private sector to universities and laid the foundations for what would become the ARPANET.

The Atlantic cable of 1858 and Sputnik of 1957 were two basic milestone of the Internet prehistory. You might want also to take a look on the Telecommunications and Computers preHistory

The Internet as a tool to create "critical mass" of intellectual resources

To appreciate the import ante the new computer-aided communication can have, one must consider the dynamics of "critical mass," as it applies to cooperation in creative endeavor. Take any problem worthy of the name, and you find only a few people who can contribute effectively to its solution. Those people must be brought into close intellectual partnership so that their ideas can come into contact with one another. But bring these people together physically in one place to form a team, and you have trouble, for the most creative people are often not the best team players, and there are not enough top positions in a single organization to keep them all happy. Let them go their separate ways, and each creates his own empire, large or small, and devotes more time to the role of emperor than to the role of problem solver. The principals still get together at meetings. They still visit one another. But the time scale of their communication stretches out, and the correlations among mental models degenerate between meetings so that it may take a year to do a week’s communicating. There has to be some way of facilitating communicantion among people wit bout bringing them together in one place.
