Prince Harry on Thursday said social media was stoking a 'crisis of hate,' and urged companies to rethink their roles in advertising on digital platforms. In an opinion piece for U.S. business magazine Fast Company headlined 'Social media is dividing us. Together, we can redesign it,' Harry said that social media, as it currently stands, is 'unwell'. The former senior royal said he and his wife, Meghan, have spent the past few weeks working with business leaders and marketing executives on the issue to try and enact positive change.
