The iTunes Store was the source of more than a quarter of US music sales during 2009, even when squared off against combined digital and retail competition, figures from the International Federation of the Phonographic Industry show. Apple contributed to a modest 1.1 percent growth in domestic digital sales, and a 9.2 percent increase for digital internationally, pushing the sector to $4.3 billion. The music industry as whole has continued to decline however, falling 7.2 percent to be worth $17 billion.
