This statistic shows Instagram's registered user numbers from December 2010 to April 2012. Instagram, a free photo-sharing app, was launched in Apple's App Store in October 2010 and hit 1 million users in December later that year. The startup reported "over 30 million" users in April 2012, shortly before Facebook announced its acquisition of the company for approximately 1 billion U.S. dollars in cash and stock.
Instagram is an online photo-sharing and video-sharing social network that enables users to take pictures and edit them with digital filters. Pictures can be shared via a personal photo stream or to other social networks. The network was originally designed as a mobile app but content can also be viewed on desktop PCs via online browser. Current Instagram penetration among U.S. smartphone users is about 23.9 percent. Overall, the service appeals to younger demographics – 37 percent of U.S. internet users between the ages of 18 to 29 access this service with usage declining towards older groups. Due to the visual appeal of the medium, many celebrities have started using Instagram as well. Similar to following celebrities on Twitter, the appeal of Instagram is the sharing of information and pictures in a seemingly direct setting. Brands have also recognized Instagram’s potential for advertising as 65 percent of leading brands have an active account.
