What is Instagram?

Instagram is a photo-sharing application that was recently purchased by Facebook for a whopping $1 billion. With Instagram, you use an app to take a photo with your mobile phone, apply a filter to that photo, then upload it and share it on various social media sites. Instagram photos have a retro, quirky vibe, but the real advantage is the ease with which you can share photos across social platforms. And while it’s fun for individuals to use, some of the world’s biggest brands are using Instagram as a marketing tool to engage customers and create a sense of community through visual storytelling.
