100 million active users a month, up 10 million from the 90 million reported 5 weeks ago. It is proof enough that the ToS debacle is clearly behind them with only some legal clean-up remaining.
If you use the search feature on phoneArena, you can find a story from December 22nd before the Android version launched, before Instagram was a household word. At the time, Instagram had hit 1 million users just three months after it was launched for the Apple iPhone. It wasn't until the Android version of the app was available that the whole thing started snowballing. Over 1 million Android users downloaded the site in less than 24 hours which became 10 million in 22 days. But even before that happened, Facebook bought Instagram for what turned out to be about $750 million in stock. And the growth continued.
The only question mark that follows Instagram is the musical question about how Facebook will justify its purchase of the site. Somehow, someway, it must be monetized because Facebook answers to a higher authority-it's stockholders. Besides, reaching 100 million people definitely has a value to other companies. Unlocking that value will be the key to Instagram's financial growth. Its subscriber growth already seems pretty certain.
