Google acquired Keyhole Corp., a digital mapping company.

If you don't have the time, here's the highlight:

"With Keyhole, you can fly like a superhero from your computer at home to a street corner somewhere else in the world - or find a local hospital, map a road trip or measure the distance between two points," said Jonathan Rosenberg, vice president, Product Management. "This acquisition gives Google users a powerful new search tool, enabling users to view 3D images of any place on earth as well as tap a rich database of roads, businesses and many other points of interest. Keyhole is a valuable addition to Google's efforts to organize the world's information and make it universally accessible and useful."

Hmmm... Do I see competition to MapQuest?
