Now, an "app gap"

Screen Time Higher Than Ever for Children, Study Finds - NYTimes.com

The study, by Common Sense Media, a San Francisco nonprofit group, is the first of its kind since apps became widespread, and the first to look at screen time from birth. It found that almost half the families with incomes above $75,000 had downloaded apps specifically for their young children, compared with one in eight of the families earning less than $30,000. More than a third of those low-income parents said they did not know what an “app” — short for application — was.
