As the Internet continues to grow and evolve, it becomes further intertwined within our daily lives. The Internet's transnational and horizontal nature, however, is at odds with traditional vertical governance structures, making its governance particularly challenging. Increased cooperation involving a multitude of actors and networks will prove key in addressing current and future Internet issues. This presents an opportunity for those who study diplomacy — especially public diplomacy — to help global stakeholders to explore new channels for effective communication and collaboration. With this in mind, faculty at the Annenberg School for Communication and Journalism at the University of Southern California (USC), in collaboration with the Internet Corporation for Assigned Names and Numbers (ICANN), held their first USC Annenberg Spring Institute in Internet Diplomacy from 13-19 March 2016, in Los Angeles, California.
