Apple announced today that iTunes downloads have now topped 5 billion. I posted back in January 2007 that iTunes had hit 2 billion purchases…
I note we’re now comparing downloads with purchases- which may or most likely may not- be the same thing, but the growth curve looks very impressive:
It’s worth highlighting that the number of weeks required for the second 2 billion downloads took less than half the time that it took to reach the first 2 billion…hence the exponential curve, not a straight line…the rate of change growth is accelerating… Ray Kurtzweil would be pleased to see exponential growth in action.
