LONDON — The growth in digital music sales is slowing considerably, falling into the single digits for the first time since record companies began making significant amounts of money online in 2004.
The International Federation of the Phonographic Industry said in its annual report that digital sales increased by 6 percent in 2010 — only half the growth rate in 2009 and far from the explosive expansion seen in earlier years. The federation values the market in legal digital music at $4.6 billion, but says the trade in unauthorized content remains much more important.
