SYDNEY (Reuters) -Australia has launched a multimillion-dollar marketing campaign that depicts its world-first ban on social media for teenagers as "for the good of our kids" ahead of its December start date. The A$14 million ($9.05 million) campaign, titled “For The Good Of”, will roll out across TV, billboards, and “ironically” social media starting Sunday, Communications Minister Anika Wells said on Tuesday. Wells said the campaign aims to spread awareness about the changes coming for families, encouraging parents to “start having conversations” about the ban with their children.
