Kids pack in nearly 11 hours of media use daily a report for CNET by Larry Magid.
George Siemens has written this:
"Kaiser Family Foundation has a new report available on youth and technology. Overall, it's not a surprising report - basically, if they're awake, they're online. Media consumption increased in almost every domain - web, TV, music, games, etc. Print was down. Two parts of the report were interesting - though mainly for lack of useful information or clear correlation: distinction in media use among whites, African Americans, and Hispanics...as well as a bit of a psychological profile on high media users (basically, they're less happy, have poorer grades, and have more issues)."
From eSchoolNews this post: Technology gives kids constant media access
The Young and the Digital references the book: Watkins, S. C. (2009). The Young & The Digital: What the Migration to Social-Network Sites, Games, and Anytime, Anywhere Media Means for Our Future. Boston, MA: Beacon Press.
I'll post other commentary links as I find them.
