News discourse as a source of metaphorical creativity in political cartooning

It is through news reports in the press or on television, radio or the Internet that people learn most of what they know about their environment or the world beyond their daily experiences. This paper raises the question: to what extent can a trending topic in news discourse become the source of metaphorical creativity, and which factors contribute to this fact? It uses the systematic analysis of multimodal metaphors in a corpus of political cartoons. The genre conventions of the political cartoon generate a particular form of engagement with the news, which in turn shapes the metaphors that political cartoonists use in their work. An editorial or political cartoon is a text, especially one in a newspaper or magazine, concerning a topical event and therefore, by definition, plays a crucial role in the reproduction of knowledge. Finding a fresh angle on a breaking news story and using this to create another piece of media content, such as an editorial or political cartoon, is often referred to as news-jacking. The question is not whether topical news stories are reproduced by journalists — it is whether they offer unique opportunities to journalists, influencing their choice of metaphors. A comparative study of cartoons about a range of topics across different cultures would deliver useful insights into how topical news items may shape the metaphors that political cartoonists use to offer expert comment. In so doing, this paper moves beyond the confines of conceptual metaphor theory (CMT), presenting fundamental challenges to a theory that was originally developed based on linguistic and artificial data.
