LO and Behold

A note recording the first message ever sent over the ARPANET

At 10:30 pm on October 29, 1969, the first message was sent from one computer to another via the ARPANET system. The historic transmission? “L.O.” Why? Because the sender, Charles S. Kline (whose initials you see in the log note above), was trying to write “LOGIN” when the system crashed at the letter G.

At this point in history, telephones were for communicating, and computers were for data processing. That is, until a few scientists realized computers should be able to talk with one another.

And here we are, 40 years later.
