Only 16 percent of Americans over the age of 13 are using devices besides their home computers to download software apps, music, video, and other entertainment content from the Internet, according to a new report by The NPD Group. The report found three-quarters (75%) of iPhone and iPod Touch users are connecting to the Internet to download entertainment content and apps, compared to 19 percent of game console users and 17 percent of Blu-ray Disc (BD) set-top users.
