Instagram is an online photo-sharing and social networking service that enables its users to take a picture, apply a digital filterto it, and share it on a variety of social networking services, including its own. A distinctive feature is that it confines photos to a square shape, similar to Kodak Instamatic and Polaroid images, in contrast to the 4:3 aspect ratio typically used by mobile device cameras.
It was created by Kevin Systrom and Cheyenne Foster and launched in October 2010. The service rapidly gained popularity, with over 100 million active users as of September 2012. Instagram is distributed through the App Store and Google Play. Support was originally available for only the iPhone, iPad, and iPod Touch; in April 2012, support was added for Android camera phones running 2.2 Froyo.
In its largest acquisition deal to date, Facebook made an offer to purchase Instagram (with its 13 employees) for approximately $1 billion in cash and stock in April 2012, with plans to keep it independently managed. Britain’s Office of Fair Trading approved the deal on August 14, 2012, and on August 22, 2012, the Federal Trade Commission in the United States closed its investigation, allowing the deal to proceed.On September 6, 2012, the deal between Instagram and Facebook officially closed.
