According to news value theory, journalists select events for news production that contain so-called news factors (Galtung & Ruge, 1965).
proximity (geographical, cultural, or economic distance between an event and the country in which it is reported),
continuity (duration of news coverage),
prominence/influence (publicity and/or power of persons, groups, or institutions),
personalization (portrayal of single persons),
reach (number of persons affected),
unexpectedness (unpredictability),
damage (negative consequences), and
controversy (portrayal of disagreement)
