Summary

Shortly after its emergence as a tool for participatory journalism, online commenting became a popular format for audience public discourse and a subject of controversy for professional journalists. The early 21st century has seen a constant growth in research considering how online comments have influenced journalism by providing new ways to understand the perspective of the audience, by changing the routines and practices of the newsroom, and by encouraging a reconsideration of how content influences readers. News audiences, generally, have been relatively quiet and passive in the past, but online comments have given them the opportunity to speak alongside journalists on professional platforms. This shift in news-mediated public discourse has the potential to reshape the journalist−audience relationship in substantial ways. The research on commenting has provided new evidence on how journalistic practices are changing, how people perceive and process information online, and how journalists negotiate technological change while trying not to upend the profession. However, there is a need for more research that explores critical questions related to comment quality, changing journalistic norms, and the relationship between journalist identity and technology. Online commenting has the potential to help fulfill the journalistic norms of providing a space for public discourse and promoting diverse views from within the community. This potential, however, is reliant upon journalists who uphold the civic function of journalism’s role.
