It's official. Instagram is worth $1 billion dollars (at least since Facebook acquired it.)
For those of you who didn't know, Instagram is a mobile photo sharing app that gained popularity quickly since it started close to 2 years ago. It has about 27 million users from fans with iOS devices alone. With the launch of the app for Android phones last week, Instagram clocked-in 1 million registered users in 24 hours. That is growing by the minute.
