Media Studies people are now beginning to use the word “trope” to refer to those items TV and other media people use to call upon elements the audience already generally knows to bring them into the story. As the site TVtropes says: “Tropes are devices and conventions that a writer can reasonably rely on as being present in the audience members' minds and expectations. On the whole, tropes are not clichés. The word clichéd means "stereotyped and trite." In other words, dull and uninteresting. We are not looking for dull and uninteresting entries. We are here to recognize tropes and play with them, not to make fun of them.” [Source: TV Tropes http://tvtropes.org/pmwiki/pmwiki.php/Main/HomePage] Or, Anita Sarkeesian of Feminist Frequency defines a troupe as “A troupe is a common pattern in a story or recognizable attribute in a character that conveys information to the audience.”
For geographers the term would include the place elements used by media people. How is a story of California or New York City told among media presentations. Heavy crime in New York city would be a trope used by many shows to create believability among the viewers. The image part of the standards would relate to tropes. The South Pacific as paradise is a trope.
