Ward Christensen brought his Computerized Bulletin Board System online 33 years ago today. From Wikipedia:
In January 1978, Chicago was hit by the Great Blizzard of 1978, which dumped record amounts of snow throughout the midwest. Among those caught in it were Christensen and Randy Suess, who were members of CACHE, the Chicago Area Computer Hobbyists’ Exchange. They had met at that computer club in the mid 1970s and become friends.
Christensen had created a file transfer protocol for sending binary computer files through modem connections, which was called, simply, MODEM. Later improvements to the program motivated a name change into the now familiar XMODEM. The success of this project encouraged further experiments. Christensen and Suess became enamored of the idea of creating a computerized answering machine and message center, which would allow members to call in with their then-new modems and leave announcements for upcoming meetings.
However, they needed some quiet time to set aside for such a project, and the blizzard gave them that time. Christensen worked on the software and Suess cobbled together an S-100 computer to put the program on. They had a working version within two weeks, but claimed soon afterwards that it had taken four so that it wouldn’t seem like a “rushed” project. Time and tradition have settled that date to be February 16, 1978. Christensen and Suess described their innovation in an article entitled “Hobbyist Computerized Bulletin Board” in the November 1978 issue of Byte Magazine.
