In 2008, iTunes became the second-biggest music retailer in America—second only to Wal-Mart. Half of Apple's current revenue comes from iTunes and iPod sales, with 200 million iPods sold and 6 billion songs downloaded. For these reasons, Apple has been ranked No. 1 on Fortune magazine's list of "America's Most Admired Companies," as well as No. 1 among Fortune 500 companies for returns to shareholders.
