A jury decided Tuesday that Apple wasn’t trying to monopolize digital music when it added FairPlay, a digital rights management technology, to songs it sold on iTunes. The class-action suit against Apple was a decade in the making, but it took jurors just three hours to reach a verdict: Apple wins. The lawsuit covered iPods purchased between September 2006 and March 2009, when only songs purchased in iTunes or imported from CDs would play on the devices.
