This section examines how the historically established institutional foundations of journalism ethics have eroded in the age of digitalisation and how this erosion has become particularly fragile and visible in the field of sports journalism. It discusses how the institutional structures established by modern and traditional journalism around ethical principles such as accuracy, objectivity, public interest, source responsibility and accountability operate through news centres, editorial hierarchy, professional organisations and self-regulation mechanisms, and then analyses the dynamics through which the digital media ecosystem weakens these structures. The study reveals how processes such as platform capitalism, algorithmic ranking logic, the speed regime, the click and engagement economy, the post-truth information regime, and ‘second-hand journalism’ based on anonymous sources have transformed journalism's claim to truth and its public oversight function. The study argues that this transformation is embodied in sports journalism through transfer journalism, phenomenon culture, club media, fan pressure, and digital lynching practices; conceptualising this field as a laboratory for the ethical crises of the digital age, while also proposing verification regimes, institutional relationships, educational models, and specific ethical principles for sports journalism, aiming to develop a normative framework for adapting journalistic ethics to digital conditions.
