Andrew Duffy, Rich Ling, Nuri Kim and Edson Tandoc, Jr. came together on a three-year research project into news as it is created, distributed and consumed on smartphones. They are colleagues at the Wee Kim Wee School at Nanyang Technological University, Singapore, specialising variously in news journalism, mobile communications technology and political communication, and their impact in society.
