Community Memory (CM) was the first public computerized bulletin board system. Established in 1973 in Berkeley, California, it used an SDS 940 timesharing system in San Francisco connected via a 110 baud link to a teleprinter at a record store in Berkeley to let users enter and retrieve messages. Individuals could place messages in the computer and then look through the memory for a specific notice.
While initially conceived as an information and resource sharing network linking a variety of counter-cultural economic, educational, and social organizations with each other and the public, Community Memory was soon generalized to be an information flea market,[1] by providing unmediated, two-way access to message databases through public computer terminals.[2] Once the system became available, the users demonstrated that it was a general communications medium that could be used for art, literature, journalism, commerce, and social chatter.
