Google Maps to Offer View of the Past
Thursday, 24 April 2014 | by Pat's Picks

It wouldn’t be a huge surprise if Google ends up being the company to figure out time travel. But for now, Google is offering a new feature of Street View that allows you to look through images dating back to 2007. If you see an hourglass in the upper left corner of the Street View screen, there is old imagery available. The feature is rolling out globally. The Wall Street Journal says the time machine will eventually be available in almost every location that has a Street View.
