Four years (and one day) ago, Kevin Systrom posted the first ever photo to Instagram, then a new social network with an uncertain future and exactly one photo of a cute dog in its archives.

Here's a neat piece of photo trivia you can throw out the next time there's a lull in conversation at a party: Instagram wasn't originally called 'Instagram.' In fact, it wasn't even a photo sharing app. Instagram was initially called 'Burbn' (after the Whiskey) and it was a check in app ala Foursquare.
