'Apple this morning announced a new set of parental controls for iOS devices at its WorldWide Developer Conference this morning in San Jose. The company had already acknowledged back in January that it had new, more robust parental control features in the works, following an open letter posted by two large Apple shareholder groups, Jana Partners LLC and the California State Teachers’ Retirement System.
The letter from the influential, activist shareholders mentioned recent research from child development experts whose studies have found links between the use of electronic devices by kids, and negative effects on concentration, emotional health, sleep and empathy. One study even found a link between time spent on devices and teen suicide, with teens who spent three or more hours per day on devices at higher risk than those who used them for an hour or less.'
