About VirtualCallboard
VirtualCallboard was first conceived in 2003 by Samuel Anderson. While employed as a stage management intern, he was delegated the responsibility of creating a small webpage to post rehearsal schedules and other company information online. The idea that became VirtualCallboard soon blossomed as he realized the incredible potential for disseminating information through the internet.
Originally dubbed VirtualPSM (Virtual Production Stage Manager), development on this full-featured, interactive, and intelligent platform began. The vision for VirtualPSM was simple; allow company members and stage managers to quickly and easily access and interact with information that pertains to them.
VirtualPSM was also uniquely developed. While most software is written by disconnected programmers sitting down over a concentrated period of time, VirtualPSM was incrementally developed over 3 years while being used in real world theatre companies.
In mid-2006, VirtualPSM was renamed VirtualCallboard to give a more universal, descriptive, and memorable name to the service.
