Chapter 3 Technology of Electronic Commerce 3.1 A short history of the Internet and the web The Internet was the result of some visionary thinking by people in the early 1960s who saw great potential value in allowing computers to share information on research and development in scientific and military fields. J CR Licklider of MIT, first proposed a global network of computers in 1962, and moved over to the Defense Advanced Research Projects Agency(DARPA) in late 1962 to head the work to develop it Leonard Kleinrock of MIT and later UCLA developed
