So much for in-app advertising being a non-sustainable business mode. Backflip Studios, developers of the popular Paper Toss and Ninjump games for iPhone, is making half a million dollars per month from in-game ads alone. The company dramatically increased ad revenue since last May, when they confirmed they had managed to make $1 million in six months.
Backflip generated more than 45 million installs on iOS, 5.5 million on Android devices.
