Facebook and Snapchat are trialling a new, more direct way to help young people bullied online, following an intervention by Prince William.
The social media platforms will help those in need of emotional support to access counsellors.
The prince, together with tech firms, children's charities and parents, is also introducing the equivalent of a Green Cross Code for the internet.
It tells young people to "stop, speak, support" when online.
The aim is to encourage them to stop negative behaviour, tell a responsible adult and support victims of bullying.
Other firms, including Google and EE, have also taken part in the project.
