Snapchat allows users to send and receive media that disappears after a recipient has opened it, laughed, and - if it's really good - taken a screenshot. It's a nice way to communicate and share content without having to deal with storing and organizing everything that you upload, but sometimes you may want to share a photo with all of your friends at once. Snapchat is rolling out a new feature that lets you share such content for up to 24 hours in a timeline that everyone can see. This timeline is your Story, and Snapchat has released a series of trailers to help you familiarize yourself with it.
Okay, the trailers are more about showing off stories than Stories, so I'll break it down. Now when you take a Snapchat photo or video, there's a new icon at the bottom that looks like a stack of photos with a star on them. Tapping this will prompt the app to ask if you want to "Add to Your Story." By default your stories are only visible to friends, but you have the option to make them publically available.
For anyone who is curious, there is a second and third trailer available that doesn't reveal anymore of the app than the first one did. As always, Snapchat doesn't cost anything to use, so go forth and make some stories.
