WhatsApp Surpasses 400 Million Monthly Active Users

WhatsApp announced another major milestone today: on the heels of its October claim that it had hit 350 million active monthly users, it’s now announcing that it has surpassed the 400 million mark in the same category. It’s 50 million new users in two months, and 100 million new users in the past four months alone. Clearly, the number of people who aren’t active users but have downloaded the app is much higher, and may mean that WhatsApp is leading the charge in the third party messaging war, which, if the numbers are anything to go by, is very evidently picking up steam.
