Commercial forces saw the computer's use, but did not originally develop them. Sure, market forces have pushed processor and graphics tech, but this is a relatively new phenomenon. From 1946 (ENIAC) to 1977 (Apple][, TRS-80), the home PC was no driving force. Computing foundations in both hardware (transistors, size reduction, storage, etc) and software (OS's, languages, databases, communication protocols) resulted from either R&D or contracts funded by the military. Without these building blocks, computers would not be commercially viable.
