Looks like Snapchat isn’t just competing with Facebook-owned Instagram. Facebook just announced that its own Facebook and Messenger Stories have now reached 300 million daily active users. A user counts as one person, so this means they won’t be counted twice. Facebook didn’t specify the breakdown between the apps though, but it must be noted that Facebook Story is automatically posted to Messenger. At the moment, Snapchat gets 188 million daily active users.
During the same announcement, Facebook has announced it will start rolling out ads in Facebook Stories similar to how Instagram Stories ads work.
