One of the first big milestones in this transformation took place in November 2004 when Google acquired a tiny and little-known 3-D mapping startup called Keyhole Inc. Google paid an undisclosed sum for the company, immediately absorbed it, and began turning its tech into what we now know as Google Earth. The acquisition would have gone unnoticed, had it not been for one not-so-tiny detail: Keyhole Inc was part-owned by the CIA and the "National Geospatial-Intelligence Agency" (NGA), a sister agency to the NSA. Keyhole Inc also had one major client base: US military and intelligence agencies.
Google is like a cheat code for intelligence gathering.
