Snap is the company that owns Snapchat, the photo- and video-messaging app launched in 2011. Each post on Snapchat is also called a Snap. Users can add filters, text, drawings, or emoji to their content before sending it. Direct messages last only up to 10 seconds before they disappear forever and are erased from the company’s servers. Snap Stories allow users to share replayable Snaps for up to 24 hours.
