Whether it is significant or not is another matter entirely.

Still, I'm skeptical. The link doesn't really say In-Q-Tel influenced Google directly, I especially don't see evidence for influence during Google's early years.

It appears Keyhole (a company G acquired in 2005, who's software became Google Earth) was funded in part by intelligence money. Google went public in 2004, so they were already beholden to public shareholders by the time of that acquisition.

Besides, Keyhole just made good mapping software. DARPA funds lots of robotics labs, but I wouldn't say Berkeley and CMU are any more a part of the US intelligence apparatus than I am as a tax payer. Some work they do has utility to the gov, so the gov funded it. That doesn't make their efforts direct intelligence work.
