Facebook is winning the race to bring Snapchat's Stories format to the rest of the world before its originator. WhatsApp Status, its version of Snapchat Stories, now has 250 million daily active users. That's despite it being relegated to a secondary dedicated tab in the app, opposed to being front and center on the home screen like Instagram Stories which also now has over 250 million users.
Snapchat by comparison only has 166 million daily users of its entire app. That include Snapchat's private messaging feature that benefits from "Streaks" which uses gamification and emoji badges to incentivize friends to send at least one Snap back and forth each day.
