"Witness: The Power of Story" was a social impact campaign by Viacom in partnership with the human rights organization WITNESS. The campaign aimed to inspire people to use video for social change by highlighting Viacom's own pro-social initiatives across its brands, such as MTV's "Look Different" and VH1's Save The Music Foundation. We used massive projection mapping on iconic NYC buildings to interrupt busy New Yorkers and literally show them the power of visual story.
