Here are the stats:

  • Age: 9 years
  • Units sold: 278,545,000
  • Net sales: $47,833,000,000

Note the seasonal patterns of quarterly sales in the chart, with Sonic-the-Hedgehog-style Christmas spikes. Note also the major inflection points, when sales accelerated:

  • Q1 2004: iTunes for Windows
  • Q4 2004: iPod mini, clickwheel, overseas expansion
  • Q2 2005: iPod shuffle
  • Q1 2006: iPod nano
  • Q1 2007: Entire line overhauled
  • Q1 2008: iPod touch

By 2006, the iPod was Apple’s (AAPL) single largest source of revenue, bigger than the Mac. Today it accounts for less than 10%, eclipsed by the iPhone, the iPad and the resurgent Mac. See Horace Dediu’s chart below (he’s got an updated version here):
