Who invented optical fibre? We need to trace back to the times when it was designed from if we desire to understand that invented fiber optics. IS/VR sounds like an US military funded project. In the format wars of the 1920s, however, the far more reliable sound-on-film method (or "optical sound") eventually won out and became the industry standard until the digital revolution.
