It was 40 years ago today..
Arpanet was the military precursor to what we now know as the internet (the term "internetting" would not be coined until 1977).
Anyway, at 10.30pm precisely, the first message was sent over the Arpanet between the University of California, Los Angeles, and the Stanford Research Institute by student Charley Kline. The message itself was the word "login". The "l" and the "o" transmitted without problem but then the system crashed. So, trivia fans, the first message transmitted over the internet was "lo".
It will never catch on...
