Instagram has reached 700 million active users, and its growth has been speeding up. The app hit the new user mark just four months after reaching 600 million, and the introduction of Instagram stories in August may be a major contributor to its accelerated growth. The feature has a reported 200 million daily active users compared to Snapchat’s 161 million. Overall, Instagram now has twice the user base of Twitter and is quickly approaching the coveted 1 billion user mark that Facebook, WhatsApp, and Messenger have reached. (TechCrunch)
