The term 'culture' first made its appearance in our discussion in Chapter 3 when we described the C-space, a creation that brought together the codification and diffusion dimensions of the I-space. There, we justified our use of the term - at least provisionally - by observing that culture has something to do with the way that information is structured and shared within and across definable populations. Codification could thus be made to serve as a proxy measure for structuring, and diffusion could do duty for sharing. The focus in Chapter 3 was on communication processes and for the limited purposes of that discussion our working definition of culture was adequate.
