Happy Birthday ARPAnet! 40 Years!

40 years ago today at about 9pm on October 29, 1969 , two programmers sat 400 miles apart and sent information between their two computers. The first word, “LOGIN” was sent at that time. Well, actually only “LO” was sent, before the Stanford Research Institute computer crashed. They worked on the problem and about 90 minutes later at around 10:30pm, the full word LOGIN was sent to the other computer: and the precursor to what we now know as the Internet was born.

SRI, then known as the Stanford Research Institute, hosted one of the original four network nodes, along with the University of California, Los Angeles (UCLA), the University of California, Santa Barbara (UCSB), and the University of Utah. The very first transmission on the ARPANET, on October 29, 1969, was from UCLA to SRI.

ARPAnet evolved into what soon became the Internet that we all know, love and depend on for information and freedom of expression.
