Here is their blurb on why they exist:
Common Sense Media is dedicated to improving the lives of kids and families by providing the trustworthy information, education, and independent voice they need to thrive in a world of media and technology.
We exist because our nation's children spend more time with media and digital activities than they do with their families or in school, which profoundly impacts their social, emotional, and physical development . As a non-partisan, not-for-profit organization, we provide trustworthy information and tools, as well as an independent forum, so that families can have a choice and a voice about the media they consume.
Sounds good to me - Anyone with children should be checking out the Common Sense Media website. They have some great recommendations and advice regarding children and today's technology, movie ratings, TV shows, Books, Website ratings, and so forth.
This is the only technology Julianna knows or cares about right now.
