This study is aimed at investigating the impact of security threats on the freedom of expression of Pakistani Television (TV) journalists. It has been observed that a growing trend of curtailment of freedom of expression is becoming new normal in the country. One of the significant problems related to freedom of expression in Pakistani media has been attacks against journalists. Pakistan Press Foundation recorded that 73 journalists have been killed since 2002 (IPEX, PPF and RIDH, 2017). This study has identified the sources and nature of security threats to Pakistani TV journalists. These security threats include threats from owners to threats from secret agencies. The study has been done under the conceptual umbrella of Social Responsibility Theory since Normative Theory deals with agents of control that also govern the laws and regulation and put check on the press freedom. The qualitative research method was adopted to conduct this research. The data was collected from a group of 25 journalists, belonging to major TV news channels of Pakistan through purposive sampling. Semi-structured in-depth interviews were conducted to gather responses. The data was analyzed through Interpretative Phenomenological Analysis technique. All responses were transcribed as verbatim, from which exploratory notes were prepared to derive emerging themes which were further categorized into sub-themes. The data revealed that the respondents not only had concerns regarding their job security rather they were also stopped from covering different packages. The research also presents recommendations to ensure maximum free expression for these journalists.
