Apple's iTunes today reached the 1 billion song mark, setting an industry milestone for sales of digital music from its popular online store. The industry-leading iTunes Music Store sold its billionth song at just after 12:30 a.m. on Thursday, February 22nd--less than three years after its launch in April of 2003. Although the company did not provide any details on the winner, it celebrated with a note on its homepage: "To every iTunes Music Store customer, thanks a billion. 1 billion songs have been downloaded from the iTunes Music Store." The company launched its billion song promo earlier this month and offered a 20-inch iMac, 10 60GB iPods, and a $10,000 iTunes Music Card as well as a full-ride scholarship in the winner's name to a world-renowned music school.

“Music lovers like you in 21 countries around the globe have purchased one billion songs from the iTunes Music Store. And for helping us reach this massive milestone in digital music history, we’d like to thank you,” Apple wrote in a note on its website.
