It was the commercialization of a project from the BBC's Interactive Television Unit called 'Future Worlds'. Future Worlds was investigating how to create video content that could be used in a traditional linear documentary and also in a hyper-linked computer-based environment. I worked at the BBC for all of three months before the ITU was spun off into an independent company, the MultiMedia Corporation. MediaMaker was published by MacroMind, and I went along with it to San Francisco.
