Keyhole, Inc

Keyhole, Inc., founded in 2001, was a pioneering software development company specializing in geospatial data visualization applications and was acquired by Google in 2004. Initially launched as a spin-off of Intrinsic Graphics, first round funding came from a Sony venture capital fund and others, additional capital came from an NVIDIA bundling deal, from the CIA[citation needed] (via its venture-capital appendage, In-Q-Tel) and from angel investor Brian McClendon[citation needed] (who later came on as a board member and VP). Keyhole's marquee application suite, Earth Viewer, emerged as the highly successful Google Earth application in 2005; other aspects of core technology survive in Google Maps, Google Mobile and the Keyhole Markup Language
