Science journalism faces an issue that is part of a bigger picture of media change. The economic pressures which have seen shrinking resources available for reporting news are contrasted by the relentless rise of corporate communication and public relations. Institutional science communication has become a booming industry, operating, at least partially, by bypassing the traditional roles of journalists. To interrogate how science journalists perceive the impact of these changes on their professional roles, as well as how they navigate relationships with scientists and institutional science communicators, we conducted in-depth interviews with experienced South African science journalists. Our paper summarises the results of this study, including how journalists perceive changes in their professional identities and responsibilities. We analyse the interview data and explore the extent to which science journalists perceive themselves as "cheerleaders" for science, in contrast to critical investigators tasked with holding science and scientists to account, as well as how they operate in a world of well-endowed corporate science communication. We situate these interview findings against the theoretical background of boundary work and recent discussions about the blurring boundaries between science journalism and science communication.
