Apple’s App Store has seen various applications coming in and going out since the release of the latest iPhone. Similarly some developers have succeeded in generating a lot of revenue while others couldn’t do anything other than rubbing their hands. In the App Store, a game called ‘Trism’ has generated $250,000 in two months. The game which was developed by Steve Demeter, costs only $5. The game is very simple but the thing which made it so popular is the innovation used in it.
