Digital and social media companies such as Apple, Google, and Facebook grip the globe with market, civic, and political strength akin to large, sovereign states. Yet, these corporations are private entities. How should states and communities protect the individual rights of their citizens – or their national and local interests – while keeping pace with globalized digital companies? This scholarly compendium examines regulatory solutions which encourage content diversity and protect fundamental rights. The volume compares European and US regulatory approaches, including closer focus on topics such as privacy, copyright, and freedom of expression. Further, we propose pedagogical models for educating students on possible regulatory regimes of the future. Our final chapter invites readers to consider social and digital media regulation for both this generation and the ones to come.
