The feature works on both the app version of Google Earth and the browser-based version. To access it, tap the layers menu. Below the option to toggle 3D buildings on or off, you should see a toggle for historical imagery.

For the service's 20th anniversary, Google was inspired by a social media trend from last year in which people shared historical images of locations in Google Maps. Now, Google Earth is getting a "time travel" interface where you can see historical Street View images from almost any location.

Google announced on Tuesday that you can now access historical Street View imagery on Google Earth. Until now, you’ve only been able to access historical Street View imagery on Google Maps. Google says the launch will allow people to explore from even more viewpoints, whether it’s a bird’s-eye view or at street level.
