Fifty years ago today, on October 29, 1969, the internet was born. It was a humble beginning—a single login from a computer terminal at UCLA in Los Angeles to the Stanford Research Institute (SRI) in the Bay Area. But it was a tiny baby step that would eventually catapult the world into the information age.

Amazingly, we actually have a piece of paper that documents that important moment for the internet, first called the Arpanet because it was a project funded by ARPA. Today you probably know ARPA better by the name DARPA, the government agency that’s working on bleeding edge tech like warfighting robots and brain implants.

The computer terminal operators who were working at UCLA in 1969 kept a detailed logbook of everything that was happening as they set up their network. And in a notebook entry for “29 Oct 69″ we can see a particularly important notation at 22:30 (10:30 pm): “Talked to SRI, Host to Host.”

That sheet of paper, which currently sits at the archives of UCLA, is more or less the internet’s birth certificate—a written record of that moment when the two host computers at UCLA and SRI started communicating.

So hats off to those guys who created the internet all those years back. Without you there’d be no reason for us to be a Sacramento Marketing Agency.
