A Brief History of the Internet

• October 29, 1969 – The first message is send on the ARPANET. This record is an excerpt from the log at UCLA:
• I was supervising the student/programmer Charley Kline (CSK) and we set up a message transmission to go from the UCLA SDS Sigma 7 Host computer to the SRI SDS 940 Host computer. The transmission itself was simply to "login" to SRI from UCLA. We succeeded in transmitting the "l" and the "o" and then the system crashed! Hence, the first message on the Internet was "Lo". We were able to do the full login about an hour later.
