Both in human and mediated communication, differences can be recognized with respect to orality and literacy. Current electronic media are hybrid forms between literal and oral communication, and users are developing a mixed oral-literal communication style. Also communication products such as literature and TV series vary across countries with respect to communication style, as we will see in Chapters 8 , 9 , and 10 . To understand differences in the production and usage of cultural products, we have to understand the basic differences between oral and literal cultures and how these developed over time. We can learn by "looking at the past against the background of the present" (Goody 1987 , p. 80).Countries have trodden different paths toward literacy, and the impact of writing has never everywhere been the same. Literacy has infl uenced thought processes. Without writing, the literate mind would not think as it does, even when it is composing its thought in oral form. When speaking, people formulate their sentences in a different way than when writing. The cultural products originating in oral cultures are structured in a different way than those developed in literal cultures. These differences can be recognized in communication styles, literary genres, advertising, and electronic communication today. The traditional mass media vary with respect to literacy and orality in design and content. This chapter discusses speech, a basic form of oral communication; language; the basic elements of orality; rhetoric and how it developed from an oral form into structured persuasive public communication; and the development of literacy, reading, and writing.
