Google Earth originated as EarthViewer 3D from CIA-funded company Keyhole, which Google acquired in 2004. Google re-released the product as Google Earth in 2005.

Today, you can use Google Earth to explore the ends of the earth and everything in between and even beyond, from the depths of the ocean to 3D buildings, Mars, the Moon and more.
