Instagram announced yesterday that they had hit the milestone of 400 million monthly active users:
We are thrilled to announce that the Instagram community has grown to more than 400 million strong. While milestones like this are important, what really excites us is the way that visual communication makes the world feel a little bit smaller to every one of us.
Our community has evolved to be even more global, with more than 75 percent living outside of the US. To all the new Instagrammers: welcome! Among the last 100 million to join, more than half live in Europe and Asia. The countries that added the most Instagrammers include Brazil, Japan and Indonesia.
I can't believe its been nearly five years since Instagram launched, it really doesn't feel like it's been that long. But I was really surprised to remember that Facebook acquired Instagram in April 2012, when Instagram had "only" 40 million users. If I recall correctly, a lot of people thought Facebook was crazy to buy Instagram for $1 billion. Well, I think Facebook got the last laugh on that one, and as Forbes points out, Instagram now has more monthly active users than Twitter (316 million).
It's been a few years since I updated my Instagram growth chart, so here's an updated version.
