This lecture discusses the development of media technology and theories about how technology influences media content and audiences. It covers:
1) Walter Benjamin's view that technological reproduction changes how meaning is structured and transmitted through media like photography and film.
2) Marshall McLuhan's theory that the medium itself, not just the content, shapes societies and cultures. He coined the term "global village" to describe electronic media bringing people together.
3) Criticisms of technological determinism emerged, arguing that technology develops through social processes, not autonomously according to its own logic. Studies showed technologies can have flexible designs negotiated by social groups.
4) A critical theory of technology aims to make technology development more democratic
