This Second Amendment billboard was part of Twitter’s 2016 OOH campaign. The quiet yet provocative image of a single shining handgun among a long line of guns paired with the hashtag symbol visually evoked the polarizing issues around firearms, while also inviting in-depth conversation and participation. For this campaign, Ad Age’s Creativity said Twitter was addressing “the issues dominating the conversation” in 2016 and that the campaign “helps to make the point that the [Twitter] brand is here to keep you posted on the world’s goings-on, as they’re happening.”
