At 10:30 p.m., on October 29, 1969, a one-word message arrived at a computer console at the Stanford Research Institute. “Lo,” read the message. That was the entire content of the first transmission sent across the ARPANET. Charley Kline, a student programmer working for Professor Leonard Kleinrock at the University of California, Los Angeles, sent the message to Bill Duvall, a computer programmer at the Stanford Research Institute, and it was supposed to be “login,” but the system crashed before it could be transmitted in its entirety, sending just the first two letters.
