Yes, it’s no mistake that the team wanted to let all of us know that it’s growing internationally, the key to grabbing its “next 400M”.

80 million photos are shared EVERY DAY on Instagram, and it’s an incredible way to see all corners of the world with your roving fingertips. Indonesia, Japan and Brazil are the three countries with most Instagrammers.

Facebook’s Instagram has reached 400 million monthly active users. Not only Instagram, Facebook has now owned other most popular apps like WhatsApp, the second most popular app after Facebook.

Despite the surge in monthly users, Instagram is still far behind Facebook, the world’s largest social network with more than 1 billion worldwide users. Among the last 100 million Instagram members added since December are soccer players David Beckham and Toni Kroos, and ex-athlete/television personality Caitlyn Jenner.

For comparison, the publicly traded Twitter, whose shares are at US$26.84 at the time of writing this - just over half of its IPO price - is sitting at 316 million active users. Mobile ad revenue for Instagram is predicted to rise to $2.39 billion which will subsequently result in Instagram accounting for 10% of Facebook Inc (NASDAQ:FB)’s ad revenue that year.

A global photography community, Instagram has developed their platform in many ways over the past year.

Instagram was bought out by Facebook in 2012 and has added a number of changes since then. On the other hand, Instagram is slowly letting advertisers take some space on the network.

The company, which had 300 million users about nine months ago, said more than 75 per cent of its community lives outside the US.

Instagram was started by Kevin Systrom and Mike Kreiger on October 6, 2010.
