Google’s Marissa Mayer gave a “deep dive” presentation on Google Earth at the DLD conference in Munich yesterday (see our coverage from the first day here). Her presentation is embedded below. Lots of interesting stats and creative use of the technology: “Hundreds of millions of Google Earth downloads and activations,” and the equivalent of “1,000 human lifetimes have been spent looking at Google Earth.” Many people are now using sketchup to build 3D models.
