Google Maps' street view function has been a bit of a guilty pleasure of mine. Before moving to the UK, it was the single biggest source of information on the new location I'd chosen via proverbial dart throw. I regularly enjoyed looking at streets, then finding out what they looked like years prior. If you're as nosy as I, Google Earth has just unveiled its own version of that same tool, complete with a timelapse function to watch towns build in mere seconds.
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.
