Instagram captures more than 50 million users
Instagram's latest user numbers are sure to make Facebook a proud new papa.
More than 50 million people are now using the popular site and its mobile apps to upload and share photos with fellow users and friends. Instagram didn't officially release the news; the company's Press Centre web page still lists the number of registered users at 30 million.
Instead, the latest figure was obtained by tapping into the site's application programming interface, according to CNET's sister site ZDNet US. Instagram is apparently adding around 5 million new users per week.
CNET contacted Instagram for comment on the numbers. We'll update the story when we get more information.
The huge upswing in Instagram's audience comes hot on the heels of the company's acquisition by Facebook early last month. Facebook is shelling out US$300 million in cash and 23 million shares of its own soon-to-go-public common stock, adding up to around US$1 billion in total.
Instagram's mobile apps have contributed heavily to its healthy supply of users.
The new Android app released in early April scooped up 1 million downloads on the first day, and 5 million in under a week.
The iPhone version of Instagram has also proved popular. In December, Apple named it the iPhone app of 2011, dubbing it the year's "definitive photo-sharing app".
Instagram lets people tweak their photos through a series of filters designed to enhance and improve even a bad picture. Users can then upload and share their photos via their Instagram profile, as well as with friends on Facebook, Twitter and Flickr.
