sean_nestor writes with this excerpt from The Register: "Some date the dawn of the net to September 12, 1969, when a team of engineers at the University of California, Los Angeles (UCLA) connected the first two machines on the first node of ARPAnet, the US Department of Defense-funded network that eventually morphed into the modern interwebs. But others — including Professor Leonard Kleinrock, who led that engineering team — peg the birthday to October 29, when the first message was sent between the remote nodes. 'That's the day,' Kleinrock tells The Reg, 'the internet uttered its first words.' ...A 50kbps AT&T pipe connected the UCLA and SRI nodes, and the first message sent was the word 'log' — or at least that was the idea. UCLA would send the 'log' and SRI would respond with 'in.' But after UCLA typed the 'l' and the 'o,' the 'g' caused a memory overflow on the SRI IMP. ... 'So the first message was "Lo," as in "Lo and Behold,"' Kleinrock says. 'We couldn't have asked for a better message — and we didn't plan it.'"
