Why it was interesting
The important part was not the website. It was who could update it.
Anthony Morris records that AGM, working with ICL Germany, designed and developed a website for the Staatstheater am Gärtnerplatz in Munich in which authorised theatre staff could log into a backend, alter performance schedules and performer/cast details at short notice, and publish those changes immediately to the public site.
In contemporary language this is simply a content-management workflow. At the time, however, cultural websites were often maintained manually by external web specialists. Giving the theatre its own direct publishing route made the website operational infrastructure rather than a static brochure.
How strongly can the pioneering claim be made?
Morris remembers the project as probably the first, or among the first, opera-house websites to allow this type of direct staff editing and immediate publication. That may be correct, but it is not yet independently established. Until surviving ICL/AGM project files, archived captures or theatre documentation fix the launch date and functionality, the public claim here remains deliberately narrower: an unusually early staff-editable programme website.
