How did we share pictures before Instagram? How did we view anything with an aspect ratio greater than 1:1? Photos were rectangles? That's just ... Well, not square. But we now live in an Instagram world. The app — which spent much of its early months as an iOS-only affair — quickly grew as a mobile-only service on which you could easily take and share photos, applying any number of filters (for better or worse) in the process.
How popular was Instagram? In just a year and a half, it went from inception in October 2010 to being purchased by Facebook in April 2012 for what at the time was a jaw-dropping $1 billion. (For more on that, read Kara Swisher's excellent piece in Vanity Fair.) Instagram has since gone tit-for-tat with Twitter, Vine and Snapchat, adding the ability to send a picture directly to another user, and the ability to record and share video.
Fast forward to today, and Instagram is a staple app on Android. It's how we share our lives. It's another way we communicate. And it's showing no signs of stopping.
