The first computer bulletin board system (CBBS) was developed by Ward Christensen and Randy Seuss in Chicago, emerging from the need for better communication among local computer enthusiasts. Prior to CBBS, user-driven communication was limited, but the advent of personal computers opened new possibilities. The inspiration for CBBS stemmed from experiences with offline message systems and the idea of fostering connections between users through electronic means. Utilizing a home computer and a modem connected to a telephone line, Christensen and Seuss established a platform where users could log in, post messages, and share files. This system effectively allowed individuals to interact in a digital space, laying the groundwork for what would evolve into today's internet forums, social media, and various online communities.

CBBS quickly gained popularity among Chicago's computer users. It was the first instance where individuals could access and contribute to a collective repository of information from their own homes. The format allowed users to leave messages for one another, which were later reviewed by other users at their convenience. This system represented a significant shift in how information could be shared and communicated, reflecting the foundational principles behind modern social networking. As news of CBBS spread beyond Chicago, it inspired the creation of similar systems across the United States and around the world, changing the landscape of computer networking forever.

Over time, CBBS and similar bulletin board systems became a crucial medium for information exchange, especially before the internet became widespread. They provided a sense of community among users sharing interests in programming, technology, gaming, and other subjects. The key element of CBBS was the ability to post content and engage with other users asynchronously, a feature that is still essential in current online forums. The concepts behind CBBS have evolved into more sophisticated online platforms, but the essence of connecting individuals through shared information and ideas remains unchanged.
