Instagram (Unofficially) Hits 25 Million Users

Instagram Hits 25 Million UsersAccording to the analysis of Dirk Singer, a London-based social media stats and research blogger, Instagram now has 25 million users.  Singer noticed that individual user numbers showed up in the apps’ user profile URLs, and that these numbers – consistent across two separate apps – are most likely the unique numbers used by Instagram to identify each user.

While The Next Web cautions that counting users by account numbers is “fraught with danger,” it does appear that the mobile photo network has surpassed the 25 million user mark, though there is no official confirmation of these numbers.

In late December 2011, Instagram CEO Kevin Systrom told NPR that the network had 16 million users.  Just over two months later, it looks like Instagram has added around 9 million users. Singer credits this massive growth to a combination of good publicity – Apple chose Instagram as its App of the Year, and Barack Obama’s campaign team is using the network – and significant post-holiday adoption from those who received Apple mobile devices for the holidays.

The application is currently only available via Apple device (iPods, iPhones, iPads), but an Android version is allegedly in the works.  Once released, adoption rates are sure to increase even more dramatically.
