This paper presents a comparative analysis of the development journalism models in Nigeria and the United States, focusing on their roles in promoting inclusive policy implementation. Development journalism, a media approach that prioritizes social issues, public education, and government accountability, is critical for fostering inclusive policy and addressing developmental challenges. In Nigeria, the media serves as a vital platform for advocating policies that address poverty, healthcare, education, and governance, but faces significant challenges, including political interference and limited resources for investigative reporting. In contrast, while more diverse and independent, the U.S. media landscape is influenced by corporate interests and political polarization, limiting its effectiveness in certain areas of development journalism. The paper explores the similarities and differences between the two models, evaluating their impact on public awareness, participation, and policy change. Key findings suggest that while both countries rely on media to inform the public and drive policy advocacy, the effectiveness of development journalism is contingent upon media independence, access to resources, and political context. Policy recommendations are provided to enhance the role of the media in promoting inclusive policy processes, including strengthening media independence, investing in investigative journalism, and fostering greater public engagement through digital platforms.
