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