Now officially owned by Facebook, Instagram has seen huge growth over the past year. Believe it or not, much of its growth can be attributed to the proliferation of Android devices, considering the app just reached 50 million downloads on the Google Play Store, a large percentage of which make up the service's 100 million+ users.
The 50 million milestone was reached in 197 days, averaging 250,000 downloads a day. Many app developers would kill for that figure as a total, let alone activity over a 24 hour period.
I was so glad to see Instagram create an Android version, since most of my family and friends are Android users. My follower count skyrocketed when the app came out, making my Instagram experience all the more enjoyable.
