It's true what is said, the transforming of data into presentation can be done to a point that it begins to look like art.  This is a prime example of this.  Displaying the key items in the timeline of the iPod hardware and the iTunes software which integrated with it.  A clock chart iconifies all the key time landmarks, along with a few key facts about downloads and sales at the bottom.  An ideal output of the numbers from the Steve Jobs era of Apple products.  Thanks Filip Chudzinski!
