The children's advocacy group Children Now has on its Web site a very useful overview of what's known about the effects of interactive media use on 3-5 year olds. Although much remains unknown this clearly written publication sums up what is. For reporters who are considering writing about the controversy over children who are younger and younger using computers, the review of research provides many good experts as sources and also lays out the position of a number of non-profit and professional groups on these issues.
