David Morley was a British media researcher who specialized in audience theory. In the late 1970s and early 1980s, he conducted The Nationwide Project alongside Charlotte Brunsdon to study media audiences. The project focused on how people from different educational and occupational backgrounds interpreted and made sense of the popular BBC news program Nationwide. Initial findings found that social class alone did not determine how people decoded media messages. However, later analysis suggested interpretations were also influenced by factors like gender and race within social classes.
