The room was likely quiet, save for the hum of a S-100 bus computer and the rhythmic screech of a 300-baud modem. Ward Christensen and Randy Suess were not aiming for a revolution. They were solving a practical problem for their computer club: how to share files without driving across Chicago in a snowstorm. The system they launched on February 16, 1978, was called CBBS, the Computerized Bulletin Board System. It ran on a single phone line connected to an Intel 8080 microprocessor with 64K of RAM. One caller at a time could dial in, leave a message, or download a program. It was a digital corkboard, a niche tool.
What they built was the architectural prototype for every online forum, social media platform, and digital community that followed. CBBS established the foundational grammar of networked communication—usernames, message threads, and asynchronous conversation. It proved that computers, then seen as massive calculators for business or government, could be centers for human connection. The callers were pioneers navigating a landscape with no map, their interactions etched onto floppy disks. This was not the sleek, graphical web. It was text on a terminal, a conversation in a dark room. The scale of what would grow from this single phone line in Chicago is almost incomprehensible. Yet, in its modest, specific purpose, CBBS contained the entire premise of the social internet: that we would use these machines not just to compute, but to talk.
