17. South Korea’s parliament is considering a law that would classify online gaming as a potentially antisocial addiction alongside gambling， drugs and alcohol. The bill has won support from parents， religious groups and doctors but has alarmed the Internet industry and enraged gamers. The legislation includes provisions to limit advertising， while a separate bill would take 1% of the gaming industry’s revenue to create a fund to curb addiction. The uproar over the legislation highlights conflicting social and economic priorities in South Korea.
18. The BBC Trust has rejected a complaint about Radio I’s decision to cut down Ding Dong! The 74-year-old song， which first appeared in the soundtrack for the Wizard of Oz film， made a surprise chart entry in April as a form of protest by critics of the late Conservative prime minister. It’s described as an inappropriate “celebration of death”.

The winner after Real was made to work hard against a much-changed visiting side.

20. Kids are plugged in more than ever， through music， movies and the Internet. A New Kaiser Family Foundation survey finds young people use media for an average of 6 hours and 20 minutes every day. Over the course of a week， that is 44 hours and 20 minutes—more than a typical workweek with some overtime. It is more time than they spend on any other activity besides sleeping， including going to school. Other activities paled by comparison. Mum and dad get fewer than 16 hours of quality time with the kids each week. They exercise less than 10 hours a week and do homework for just 7 hours， right near the bottom of the list.
