One of the few universal truths of the technology world is that the key to a burgeoning format's success is unification and compatibility. Proprietary technologies breed platform fragmentation, and when products aren't compatible with each other, people don't use them, and the format dies. Take USB, for example: USB is successful as a standard because everyone uses the same connectors and licenses the same underlying technologies. You can take a USB keyboard made by one manufacturer and plug it into a motherboard built by another, and it works. The same cannot be said, however, for the majority of 3D glasses in the world, and that's a big problem for a lot of big companies.
