Here is a snapshot of their findings (page 5):

• Children have more access to all kinds of digital media,
and are spending more time during the day with them than ever before.
• Not all children have access to newer digital technologies, nor do all children use media in the same ways once they do own them. Family income continues to be a barrier to some children owning technology, even as the price of devices falls.
• Lower-income, Hispanic, and African American children
consume far more media than their middle-class and
white counterparts.
• Children appear to shift their digital media habits around age 8, when they increasingly open their eyes to the wide world of media beyond television.
• Mobile media appears to be the next “it” technology, from handheld video games to portable music players to cell phones. Kids like to use their media on the go.
