Google has used its annual Google I/O developer conference to reveal a new streaming music subscription service called Google Play Music All Access.

At the moment it’s just available in the USA and will cost $9.99 per month, although early adopters receive a $2 discount. Customers can store up to 20,000 of their own songs and listen to them alongside millions of online tracks.

The UK’s Office of Fair Trading has launched an investigation to find out whether some free web-based games and mobile applications for children are breaking the law.

It’s particularly concerned that games may include a ‘direct exhortation’ encouraging children to make a purchase or persuade their parents to buy advertised products for them, as this is illegal under consumer protection regulations.

Can mobile devices be used for game-based learning as part of the school curriculum?

This discussion was recorded in Barcelona during Mobile World Congress 2013 as part of Heroes of the Mobile Fringe. The panel was moderated by Russell Buckley with contributions from Vincent Hoogsteder of Distimo, Volker Hirsch of BlackBerry and Alina Vandenberghe of Pearson.
