The Royal Foundation, the charity organisation of Prince William, has brought together the UK's largest media and technology companies in a bid to tackle cyberbullying.
Aimed at 11- to 16-year olds, the campaign involves Apple, Facebook, Google and Snapchat, along with children's charities including NSPCC.
It establishes a code of conduct for online interactions – stop, speak, support – that aims to help young people identify harmful online behaviour and know how to respond.
The campaign's animated film was created by Ty Stanton-Jones and Ant Stamp at Livity, and animated by James Curran through Partizan. It features the rich voice of Matt Berry, star of Toast of London and The IT Crowd.
