Instagram takes the title of No. 1 free app on iTunes

With news of Facebook's acquisition and the new Android app still fresh, the photo sharing social network is now topping charts in the app store.

Instagram has terminated Draw Something's long-time reign over the No. 1 free app spot on iTunes' download charts.

"Instagram is #1 in the @AppStore for the first time ever! Thanks everyone!," Instagram announced on Twitter today.

Most likely this has something to do with Facebook's acquisition of the photo sharing app yesterday. With widespread news that the social networking behemoth laid down $1 billion for Instagram, people who weren't familiar with the app must have gotten curious.

It's been a big last few days for the 2-year-old startup. Not only did it cash in with Facebook yesterday, but it also launched its app for Android just six days ago, which resulted in 1 million downloads in just the first day.
