Dominant Flow?

At the end of the essay, when speaking of the five scapes, Appadurai asks, “Can we speak of some of these flows as being, for a priori structural or historical reasons, always prior to and formative of other flows?” He answers this by saying that it is largely context dependent. But is there the notion of a dominant flow for a particular era? Certainly looking at the influence of print media in creating imagined nations, one could say the Industrial Revolution was dominated by a mediascape. Looking at the advent of the Internet only recently, perhaps we are in an era dominated by a technoscape. Appadurai notes of “Silicon Valley in California, where intense specialization in a special technological sector (computers) and specific flows of capital may well profoundly determine the shape that ethnoscapes, ideoscapes and mediascapes may take” (21).
