Today Instagram announced that it now has more than 400 million users who share 80 million photos per day.

In less than a year, the Facebook-owned photo sharing app has added 100 million new people to its platform. The app owes most of its growth to international expansion. Of the latest to join, the majority are in Europe and Asia. However, Instagram saw the most growth in Brazil, Japan, and Indonesia, according to a blog post.

Instagram has attracted a few new celebrities as well, including soccer stars David Beckham and Toni Kroos, former Olympic athlete Caitlyn Jenner, Indonesian entertainment duo Raffi and Nagita, and South Korean rapper Choi Seung-Hyun, aka T.O.P.

Since launching five years ago, Instagram has quickly amassed a following, surpassing older social platforms like Twitter.
