Rhetorical circulation

Rhetorical circulation theorizes the ways that texts and discourses move through time and space. The concept seems to have been applied to texts sometime in the mid 1800s, and it is considered, by most scholars, to be either subordinate to or synonymous with the canon of rhetorical delivery, or pronuntiatio. It is something like newspaper circulation and magazine circulation in that it can involve print media, but it is not limited to these. In fact, any kind of media can circulate. Books can be loaned; Internet memes can be shared; speeches can be overheard; YouTube videos can be embedded in web pages.
