Google Maps turned 10 years old on Sunday—a milestone observed by Samuel Gibbs in the Guardian. See also Liz Gannes’s retrospective at Re/Code. My reaction on launch day was pretty effusive—I was blown away mainly by the user interface. But it wasn’t immediately dominant: it took roughly four years for Google to surpass MapQuest in traffic.
Meanwhile, the Pro version of Google Earth, which used to cost $400/year, is now free. Google Earth itself launched in June 2005, so is approaching its own 10-year anniversary, but it began its existence a few years earlier as Keyhole EarthViewer 3D.
Speaking of map anniversaries, National Geographic Maps is marking its centennial.
The photo above marks another anniversary: It shows Apollo 14 astronaut Ed Mitchell consulting a map during his second lunar EVA on February 6, 1971. Apollo 14 returned to Earth 44 years ago yesterday.
