There is a lot to explore here and I like EA’s freemium push with the Simpsons. A nice proof point showing how it works with Temple Run:
Right before we switched it to free in September, we had a couple hundred downloads/day at 99 cents, with some in-app purchase sales. After switching it to free and settling at No. 100 Top Free app, we had about 50,000 daily downloads, and a whole lot more in-app purchases. In fact, revenue went up 10x immediately upon switching to free, so keeping it free was a no brainer.
