Since its inception, Twitter has seemed like a 24/7 global cocktail party; the sort of thing that would appeal to information-addicted media types. But the service has evolved into a platform where news unfolds in real time. It's where the #BlackLivesMatter hashtag and subsequent movement began in 2013, following the shooting of Trayvon Martin. It's where the world turned to follow the Ferguson protests in 2014 -- and even before that, Michael Brown's death was being discussed on Twitter. There's no doubt that the service is a valuable tool for reporting, but how do you sell its benefits to the wider public? That's something Twitter is hoping to solve with a new marketing campaign.
