I find these numbers boggling. When someone says that a game like, say, Tomb Raider has sold 4 million copies I feel as though I can grasp what that means. 4 million people — that's like roughly the population of Melbourne. There is something to compare that number to. Something almost tangible. But when someone tells you that the App Store is rapidly approaching its 50 billionth download — what does mean? How can we even comprehend that? What do we compare that number to?
So the Apple App store is approaching its 50 millionth download, and they have a countdown — although technically it's a countup. Last I check it was sitting at 49.2 billion. Who knows how long it's going to take to hit 50 billion, I certainly wouldn't sit there staring at it for too long if I were you.
But it might be worth checking in on every once in a while!
