In a big train station, the National Centre for Domestic Violence and JWT London have coordinated and used JC Decaux digital outdoor network to raise awareness about domestic abuses and to urge people not to be a silent witness. How did it work? The outdoor feature a woman who lives an abusive domestic situation, with a call for action. Using their smartphones, the participants are able to control the man in dragging him away from the woman on to the other billboards. When they are separated, the screens synchronise and show the same message incitating people to intervene.
