This study focused on evaluating the credibility of state-owned radio stations in South-South Nigeria and its impact on audience trust and listenership. Recognising that media credibility is crucial for maintaining public trust and engagement, the study explored whether government-owned radio stations in the region are perceived as reliable sources of information or as biased platforms that prioritise state interests. Using the source credibility theory, the research employed a qualitative methodology which comprised in-depth interviews with twelve purposively selected journalists (two from each state capital, i.e. Benin, Asaba, Calabar, Uyo, Yenagoa, and Port Harcourt), aiming to gain deeper insights into professional perceptions of government influence and media credibility. The qualitative data were analysed using the explanation-building technique to identify themes and patterns in participant responses. The study's results provided a robust examination of how the credibility of state-owned radio programming in South-South Nigeria is perceived by its audience and how these perceptions influence listenership and trust. Thestudy also found that government ownership is widely perceived to compromise the objectivity and balance of programming on state-owned stations. Based on the findings, the study identifies a strong public demand for editorial independence, transparency, and professional autonomy in state-owned radio. Hence, it recommends structural reforms such as the establishment of independent media boards and public broadcasting charters that shield content production from political interference.
