Instagram now has 200 million monthly active users sharing 60 million photos a day, the service has announced, totaling to 20 billion photos shared since it launched in 2010, the Guardian reports.

The photo-sharing service has added around 170 million users since its acquisition by Facebook in April 2012 for $1bn, with 50 million joining in the last six months.

“From documenting a passion for jazz to the protests in Kiev, we’re continually surprised and humbled by the moments you share,” an Instagram spokesperson said in a blog post.

Since being bought by Facebook, Instagram has added support for Windows Phone, introduced Instagram Direct – a private photo sharing feature – and added the ability to share video clips of up to 15 seconds.

Facebook's chief executive, Mark Zuckerberg, also announced that the social network had passed the 1 million monthly active mobile user milestone, during a call discussing the company’s purchase of the Oculus Rift virtual reality headset on Tuesday, March 25.

Facebook had 945 million monthly active users on mobile in the fourth quarter of 2013, which generated 53% of the company’s advertising revenue in the same quarter.

Facebook’s recent $19bn acquisition of the WhatsApp mobile messaging service, as well as the introduction of Facebook Paper and other in-house Facebook mobile apps shows that the social network is focused on mobile, as more and more eyeballs migrate to the portable screen, the Guardian says.
