Bob Taylor, a contributor in the development of ARPAnet, describes it like this, "For each of these three terminals, I had three different sets of user commands. So, if I was talking online with someone at S.D.C., and I wanted to talk to someone I knew at Berkeley, or M.I.T., about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them. I said, "Oh Man!", it's obvious what to do: If you have these three terminals, there ought to be one terminal that goes anywhere you want to go. That idea is the ARPANET"

A driving factor in the development of ARPAnet, and the World Wide Web as a result, was the threat of nuclear war. The idea was that a communication system that relied on a central sender was vulnerable, and an interconnected group of computers with no central figure was not.
