More and more, organizations are leveraging mobile technology to reach the nearly half of the world's population that's under 25. This talk will highlight learnings around scaling sexual health content on mobile, looking specifically at TuneMe, a mobisite for youth engagement that began in Zambia and has expanded to Zimbabwe and Malawi. How do you reach both men and women with your content? What do you do when youth don't want to leave your Facebook site? The talk will provide solutions to these challenges and shed insights on effective ways to scale regionally.
