A video-game industry body is urging parents to use parental controls on electronic devices to prevent their children from accessing unsuitable content.
The Interactive Games and Entertainment Association represents the makers, publishers and distributors of video games, such as PlayStation and Nintendo.
Association chief executive Ron Curry says parents too often give their children responsibility for setting up electronic equipment.
As well as using the parental controls to monitor the suitability of content on a device, they can also specify how long and often their child can use it.
Mr Curry says parents can easily learn about the media their children are using by sitting down with them and joining in.
