Snapchat is a multimedia messaging app with over 158 million daily users. It was created in 2011 by Evan Spiegel, Bobby Murphy and Reggie Brown as a playful app for teens and young adults to send disappearing photos and videos. While initially popular among younger users, Snapchat's user base has grown to include older age groups as well. The app generates revenue through advertising filters and sponsored lenses that are popular with users and brands.
