To celebrate the 20th anniversary of Google Earth, you can now go back in time when scrolling with a handy 'Historical Imagery' button on the top left. Depending on how far back the technology goes, you can scroll all the way to 1984.

Google Earth is celebrating its 20th anniversary with an interesting new feature: the ability to time travel through your favorite spots with Street View. Google Earth added historical aerial imagery last year.

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.
