First Message on the Internet

This is the log of the first message sent on the Internet.

October 29, 1969

UCLA student Charley Kline attempts to transmit the text “login” to a computer at the Stanford Research Institute over the first link on the ARPANET, which was the precursor to the modern Internet. After the letters “l” and “o” are sent the system crashed, making the first message ever sent on the Internet “lo”. About an hour later, after recovering from the crash, the full text of “login” is successfully sent.
