Input: Question: What year was the company founded that created both show control and theatre sound design software which was used extensively in the theatre, theme park, display, exhibit, stage managing, show and themed entertainment industries in the 1980s and 1990s? Passage:Richmond Sound Design (RSD) created both show control (a.k.a. MSC or "MIDI Show Control") and theatre sound design software which was used extensively in the theatre, theme park, display, exhibit, stage managing, show and themed entertainment industries in the 1980s and 1990s and at one point in the mid 90s, there were many high-profile shows at major theme parks around the world being controlled by Amigas through software simply called Stage Manager which then evolved into its Microsoft Windows version called ShowMan. There were dozens at Walt Disney World alone and more at all other Disney, Universal Studios, Six Flags and Madame Tussauds properties as well as in many venues in Las Vegas including The Mirage hotel Volcano and Siegfried and Roy show, the MGM Grand EFX show, Broadway theatre, London's West End, the Royal Shakespeare Company's many venues, most of Branson, Missouri's theatres, and scores of theatres on cruise ships, amongst hundreds of others. RSD purchased used Amigas on the web and reconditioned them to provide enough systems for all the shows that specified them and only stopped providing new Amiga installations in 2000. There are still an unknown number of shows on cruise ships and in themed venues being run by Amigas.
