Despite confusion earlier in the day about NPD market share data, Apple has clarified that for the January-February 2008 iTunes was the largest US based music retailer.

“We launched iTunes less than five years ago, and it has now become the number one music retailer in the world,” said Eddy Cue, Apple’s vice president of iTunes. “We are thrilled, and would like to thank all of our customers for helping us reach this incredible milestone.”
