Instagram is copying Snapchat.

Facebook Inc.’s app has a new feature that lets people share photos and videos that disappear, the defining feature of Snapchat. Users can write over the photos and add annotations — just like in Snapchat. The product lets people post photos or videos taken throughout their day in a slideshow form, just like Snapchat Stories. They vanish in 24 hours — just like Snapchat Stories. To make it totally clear, Instagram is calling its product Stories too.

“This is the latest step in putting video at the center of all our services,” Facebook Chief Executive Officer Mark Zuckerberg said in a post Tuesday, not mentioning Snapchat. “People are already creating and sharing more video, so we’re going to make it even easier.”
