The number of people downloading music off the internet has surged again after several months of decline after the recording industry began suing consumers. “The number of U.S. households downloading music from peer-to-peer networks rose 6 percent in October and 7 percent in November after a six-month decline, according to a study of computer use in 10,000 U.S. households conducted by The NPD Group. In a separate, bimonthly survey, 12 million individuals reported getting music on the free networks in November, up from 11 million in September.”
