As reported in the Korea Joongang Daily, smartphone use among 5-19 year olds increased from just 7.5% at the end of 2010 to 67% in June of this year. As the bar chart the accompanying graphic shows (click on the graphic to see a full size version), levels of smartphone addiction among children now exceed internet addiction.
The headline of another article in The Joongang Daily is revealing: "Smartphones cause rifts in families." Of course they do. I met earlier this week with a colleague from Korea's ICT sector who mentioned to me that "..all of the kids now have LTE phones." I have argued elsewhere that the term "smart phone" is a misnomer. An LTE phone is an internet-connected computer with more capabilities than a typical desktop model. One needs only imagine the difficulties for parents of guiding their children's use of the internet. The article is worth reading.
