The Mayor of London and Ogilvy UK teamed up on a bold new campaign to address sexist attitudes and inappropriate male behavior that has led to an epidemic of misogyny and male violence against women and girls. The campaign launched with a timely film which puts the onus on men to act when they see misogynistic behavior and harassment. Built with behavioral science insights, the approach gets men to think about their own behavior, and how they’d challenge the behavior of their friends, giving every man an active role in tackling the problem and creating real change.
