BBDO New York's new campaign "See both sides of the story - BBC World" uses corner billboards to show two different perspectives.
Each billboard was wrapped around two sides of a corner. A current news photo made up most of the billboard. Viewers had to walk around the corner, looking at both sides, to grasp the complete story.
The BBC used five different news stories they thought would resonate with New Yorkers:
A U.S. soldier in Iraq guarding an oil well that is burning
Jewish settlers during a West Bank evacuation
A border patrol and Mexican immigrants
Protestors in France
Iraqi’s listening to a U.S. Presidential interview
