A new study by market researcher NPD Group found that 85% of children aged 2-14 use game consoles, and 82% of 2-to-5-year-olds play games on one or more devices, while 60% use digital music players, Gamasutra reports. NPD's Kids & Digital Content III report, which surveyed more than 3,500 kids who use electronic devices, also found that a third of the 2-to-14-year-olds watch videos such as movies and online video clips on laptops or other electronic devices, and 22% download ringtones on their cellphones. Here's more on the NPD report from Gamespy.
