The July issue of Vanity Fair has an extremely long yet fascinating overview of the birth of the Internet, developed by interviewing many of the scientists who developed it at ARPA.
On an eight-month deadline, the BBN team delivered their prototype I.M.P. to U.C.L.A. on August 30, 1969.
Leonard Kleinrock: September 2, 1969, is when the first I.M.P. was connected to the first host, and that happened at U.C.L.A. We didn’t even have a camera or a tape recorder or a written record of that event. I mean, who noticed? Nobody did. Nineteen sixty-nine was quite a year. Man on the moon. Woodstock. Mets won the World Series. Charles Manson starts killing these people here in Los Angeles. And the Internet was born. Well, the first four everybody knew about. Nobody knew about the Internet.
So the switch arrives. Nobody notices. However, a month later, Stanford Research Institute gets their I.M.P., and they connect their host to their switch. Think of a square box, our computer, connected to a circle, which is the I.M.P., 5, 10 feet away. There’s another I.M.P. 400 miles north of us in Menlo Park, basically at Stanford Research Institute. And there’s a high-speed line connecting those two. We are now prepared to connect two hosts together over this fledgling network.
So on October 29, 1969, at 10:30 in the evening, you will find in a log, a notebook log that I have in my office at U.C.L.A., an entry which says, “Talked to SRI host to host.” If you want to be, shall I say, poetic about it, the September event was when the infant Internet took its first breath.
