Snapchat is a photo messaging app launched in 2011 that allows users to send disappearing photos and videos (snaps) to friends. It reached 100,000 users by spring 2011 and was valued at $10 billion by 2014, though it currently does not generate revenue. Snapchat revolutionized social media by focusing on intimacy and exclusiveness over permanence and brought people together through live event stories and new forms of advertising.
