Apple's App Store's 5th birthday nets Infinity Blade 2 millions of new users
On the first day of the promotion alone, Infinity Blade 2 saw 1.7 million new users download the game, and estimates say that so far the promotion has led to somewhere between 5 and 7 million new users who have downloaded the game. And, even though the game was downloaded for free, the game does include in-app purchases, so there is little doubt that Chair Entertainment has profited in this past week.
Even if you don't expect that all that many new users would buy anything with the in-app system, the promotion has also led to a spike in the original Infinity Blade downloads, and that game still costs $5.99. Supposedly, downloads of that game jumped 2.5x last week, and Infinity Blade: Awakening, a $2.99 e-book bridging the plots of the two games, also saw sales rise 70% last week.
Not a bad result from having your game promoted, eh?
