“…Some studies focus on media portrayals of terrorism incidents or terrorists, whereas others examine how the media label terrorist actions and actors (e.g., Livingston, 1994;Lule, 2002;Picard & Adams, 1991;Weimann & Winn, 1994) or reporting formats and story types (e.g., Altheide, 1987;Atwater, 1987). Still other studies focus on particular terrorist organizations, such as the Irish Republican Army 450 D. Zhang et al (Viera, 1991), or a single terrorism event, such as the 11 September 2001, attacks on the World Trade Center, and the Pentagon (Li & Izard, 2003). Other scholars use gatekeeping theory to explain why mass media cover only a small number of the terrorist events that take place every day.…”
