It's been almost three years since Instagram launched their stories feature. Back then Snapchat had already been the leader when it came to ephemeral (disappearing) content. But back in 2017, Snapchat when their IPO hit the public, their user growth hit a wall. This was when Instagram Stories' user growth reached a rapid increase. Now, in 2018 they're holding steady at over 400 million users! This is double the amount of Snapchat users.
