What does it mean for democracy when a president owns a social platform, and is supported by others with major platforms of their own? Philip Napoli directs the DeWitt Wallace Center for Media and Democracy at Duke University and he joins Manoj Mohanan, interim public policy dean at Duke to discuss historical parallels to the connection between policy and media ownership, and regulation options. His book is called “Social Media and the Public Interest, Media Regulation in the Disinformation Age."
