"The authors present regional trends from Sub-Saharan Africa, the Americas, and Eastern Europe in light of global developments in investigative reporting, taking into consideration different muckraking cultures, and share examples of successful strategies of investigative media outlets. They suggest that a comprehensive and collaborative approach in supporting investigative media is needed to ensure a viable future for investigative media as well as the sector itself. For this, a model describing elements specific to the viability of investigative journalism is presented to help media startups, donors, media development NGOs identify possible areas of support."
