Social media marketing was created in 2011 by three students at Stanford University named Evan Spiegel, Bobby Murphy, and Reggie Brown. The application was first developed to allow users to message back and forth and to also send photographs that are only available from 1–10 seconds until they are no longer available. The app was an instant hit with social media members and today there are up to 158 million people using snapchat every single day. It is also estimated that Snapchat users are opening the application approximately 18 times per day, which means users are on the app for about 25–30 minutes
