Instagram Hits 10 Million Users in 355 Days - A Brief Retrospective

The Instagram developers have announced their photo-sharing service has now 10 million registered users:

Last October, we launched Instagram live in the App Store. Today, less than one year later, we’re happy to announce that the Instagram community now consists of over 10 million registered users.

The first version of Instagram, which I reviewed here, was released on October 6th, 2010, exactly 355 days ago. Last week, Instagram released a major 2.0 upgrade, which includes live filters, and updated UI, and several optimizations to the code. Here’s a quick look back at Instagram’s history in the past 12 months:

- October 6th, 2010: Instagram released on the App Store.

- December 7th, 2010: Instagram gets inline viewer on

- December 21st, 2010: Instagram reaches 1 million registered users.

- January 27th, 2011: Instagram 1.1 is out with hashtag support and some optimizations.

- January 28th, 2011: Twitterrific, a popular third-party Twitter client for the Mac and iOS, adds native Instagram support for photo URLs.

- February 8th, 2011: Instagram announces its official API.

- February 26th, 2011: The first results of Instagram’s API are in.

- March 10th, 2011: Flipboard, Apple’s iPad app of the year, adds native Instagram integration.

- March 11th, 2011: Instagram 1.5 brings new effects and News Feed.

- April 2nd, 2011: Here comes the first Instagram client for Mac based on the API.

- April 15th, 2011: Instagram 1.6 focuses on performances.

- May 16th, 2011: Instagram 1.7 gets a new profile view.

- May 23rd, 2011: Instagram announces 4.25 million users.

- May 26th, 2011: Instagram 1.8 improves the comment section.

- August 3rd, 2011: 150 million photos have been uploaded to Instagram.

- September 20th, 2011: Instagram 2.0 released.

- September 26th, 2o11: Instagram hits 10 million users.

From the timeline above, I had to exclude several of the minor updates Instagram released, or amazing third-party apps that plug into the service to extend its capabilities (not to mention celebrities and brands). And as with last year’s original release, Instagram is still an iPhone-only app.

Has there ever been an iPhone app with such terrific third-party and user support in just 355 days?
