Facebook, Twitter, Instagram, Pinterest. Since the earliest days of social media, The Times has published on a host of social platforms. Now we’re adding Snapchat Discover to the mix.

Not there yet? Fear not. Here’s a look at what it is, how it works and why we’re there.

Two years ago, The New York Times started telling stories on Snapchat, a social messaging and storytelling platform. The goal was to present our journalism in a highly visual way.

Snapchat stories are compilations of videos and photos strung together over a 24-hour period. And each frame expires exactly 24 hours after posting. The result is a visual rough cut narrative.

Since we launched, we’ve taken you to rural Angola, brought you along with us on the red carpet at the Grammys, shown you what it’s like on Air Force One. We’d tell you to go watch them on Snapchat, but of course, they’re long expired by now.
