Callboard Network

Callboard Network was an early electronic bulletin board and conferencing system operated by the University of Alberta’s Alberta Section of the United States Institute for Theatre Technology (USITT) from 1985 into the early 1990s. It served as a primary means of communication among theatre technicians across North America, long before the rise of the public Internet. It linked professionals working in live production, technical direction, stage management, lighting, and sound.^[1]
