FREECONOMICS

How have web companies like Google, YouTube and Yahoo! built successful businesses when most of their products are free?

That's the question Wired magazine's editor-in-chief Chris Anderson asks in his new book FREE. Gareth chats to him about 'freeconomics' and future business models for net content.

Chris also shares his passion for building DIY Drones. These are small unmanned aerial vehicles, built by amateur enthusiasts using 'open source' hardware.

CYBERBULLYING REPORT

This week sentencing is due in the controversial MySpace cyberbullying case in the United States.

Lori Drew, a middle-aged woman from Missouri, posed as a boy called Josh on MySpace to befriend Megan Meier, 13. When 'Josh' ended their virtual relationship, Megan committed suicide.

A Europe-wide survey earlier this year by Microsoft, suggests that almost a third of all teenagers have experienced some form of cyberbullying. Denmark was found to have the highest incidence, with 45 per cent of teenagers saying they'd been bullied online.

主播大秀 reporter Angela Saini looks at new initiatives to tackle this growing problem.
