While I'm sure there is some perverse way of defining "innovation" that can muster up enough factual basis to count as a half truth for some drunk in a gutter, I suggest you consider the less extreme position that technological development is driven by a multitude of factors and towards equally diverse goals.

First off, we can dispense both porn and video games as important technological drivers since both are realms of extremely narrow focus compared to the breadth of the military; neither can for instance be credited with driving development of automatic telephone exchanges.

The military has much more diverse needs, and could therefore plausibly drive "innovations in technology" over a large enough breadth of technologies to count. Still, the technology the military directly develops or pay for being developed is of a decidedly military nature, and as we all know the civilian sector of society is quite sizable and contains a multitude of technology unique to it, none of which are directly developed by the military.

Frankly, the fact that the Board of Longitude lead to portable timepieces does not mean the military can be credited with all advances in timekeeping henceforth.
