From around the web, some interesting news and analysis about social, tech and media:

1. There are even Beatles posters! At trend Central, a look at media that reflects the history of adolescence — including a photoblog showing teen bedroom decor. http://bit.ly/lYCvxb
2. As young as nine! Nielsen Wire reports that when asked what percentage of the apps on their phone were downloaded by their children, parents reported that 30 percent of the apps on their phones were installed by their kids. http://bit.ly/grc3oV
3. No surprise: Trailing all other age groups, teens age 12-17 watch the least amount of TV. The average American watched 34 hours 39 minutes of TV per week in Q4 2010, a year-over-year increase of two minutes. Media Post reports on other stats about users of traditional TV. http://bit.ly/ltZJ57

Here’s to a thoughtful start to your week.
