If domestic violence seems like an abstract phenomenon, this TBWA campaign from Finland will remind people that it's happening right on their doorstep.
TBWA launched an outdoor campaign for the Helsinki Police over the Christmas holidays that had a hyperlocal, reactive element to it. When a domestic violence call into 911 (which is actually 112 in Helsinki), the agency—with help from outdoor company JCDecaux—immediately put up anti-violence PSA posters on the 15 outdoor placements nearest to the home that made the call.
The posters stayed up for 48 hours before being swiftly removed again.
