Government Tied up in Bow
Chances are very good that right now you are using a technology that government developed and then had it all tied up in a bow for commercial use. That technology is Gallium Arsenide. It is in most cell phones and WiFi access points. In the 1980's it was a laboratory curiosity, then the military started to develop it for their needs, funding the development and infrastructure to produce it. They also realized that to keep their costs down the producers needed a commercial market to get volume up and prices down. So in the 1990's, it began to be commercialized and entered the cell phone market. By the 2000's the commercial market led production.
