Angry Birds Hits 50m Downloads And Plans To Spread Simple Purchases On Android
The main announcement was about “Bad Piggy Bank”. This is an in-game payment model for Angry Birds on Android which lets users either remove the ad on the free version of the game or buy the Mighty Eagle update that’s on its way.
Bad Piggy Bank will not require credit card details, and downloads purchases instantly. It does this by charging in-app purchases to your mobile phone bill. But that’s not all.
