3 Internet History In 1957, the Soviet Union launched the first satellite, Sputnik I, triggering US President Dwight Eisenhower to create the ARPA (Advanced Research Project Agency ) agency to regain the technological lead in the arms race. A special computer called an Interface Message Processor was developed to realize the design, and the ARPANET went live in early October, The first networking protocol used on the ARPANET was the Network Control Program. In 1983, it was replaced with the TCP/IP protocol developed by Robert Kahn, Vinton Cerf In 1990, the ARPANET was retired and transferred to the NSFNET (National Science Foundation Network ). The NSFNET was soon connected to the CSNET, which linked Universities around North America, and then to the EUnet, which connected research facilities in Europe. The use of the Internet exploded after 1990, causing the US Government to transfer management to independent organizations starting in 1995.

4 Internet History The conceptual foundation for creation of the Internet was significantly developed by three individuals and a research conference, each of which changed the way we thought about technology by accurately predicting its future: Vannevar Bush wrote the first visionary description of the potential uses for information technology with his description of the "memex" automated library system. Norbert Wiener invented the field of Cybernetics, inspiring future researchers to focus on the use of technology to extend human capabilities. The 1956 Dartmouth Artificial Intelligence conference crystallized the concept that technology was improving at an exponential rate, and provided the first serious consideration of the consequences. Marshall McLuhan made the idea of a global village interconnected by an electronic nervous system part of our popular culture.
