While Instagram Stories was a massive success for the company, Facebook Stories and other products saw very little user adoption for obvious reasons: teens don't want to share their everyday life with their Facebook friends, and the majority of them don't even consider it to be a "cool" place anymore.
The fact that has Facebook four distinct Snapchat-like offerings for its main social network, Messenger, Instagram and WhatsApp can be pretty confusing.
Now, when you post something on your Facebook Story, it will also appear on Messenger and vice versa, and the fusion is simply called "Stories". According to TechCrunch, not only will Stories between Messenger Day and Facebook be consolidated as of today, but Facebook is also getting rid of Direct, an ephemeral messaging feature. Going forward, all replies to Stories as well as Facebook Camera messages will be directed through Messenger. With this new feature, members of a specific Facebook Group or Event will be able to contribute to a Story that's visible to the rest of the members...
While Facebook is streamlining many facets of Stories, there is one thing it is adding: collaborative Stories for events. People will see Stories on their Event and Group pages, as well as atop their News Feed. The company says this will make it easier for users to share content across both services, while also noting that some people were already under the impression that stories posted to Messenger were also posted to Facebook.
