GM food is a highly controversial topic. Research has shown that individuals gather information on controversial issues predominately from newspapers. This thesis looks at newspaper coverage of GM food during years the 1993-2003 within four newspapers. This thesis looks at whether and how the coverage diverges and examines if that variation is influenced by specific events. The variables examined for variation include: length, number and classification of frames and sources, and bias. The data suggests that variation does exist, with newspapers located within the same country having greater correlation than those located in similar regions in different countries. All four newspapers were negatively biased to GM food, with the UK newspapers being more biased than the US newspapers. Evidence suggests the coverage of GM food is predominately event driven and episodic in nature. The events influencing coverage of GM food are different from those influencing coverage of biotechnology.
