Final answer:
Author David Lewis highlighted the application of anthropological research in understanding and analysing the advertising industry, taking into account cultural influences on consumer behaviour and the historical development of advertising methods and ethics.
Step-by-step explanation:
David Lewis utilized anthropological research to delve into the intricacies of the advertising business by comprehending the cultural elements that play a pivotal role in how products are marketed and sold. He noted the importance of anthropological insights in understanding consumer behaviour, branding strategies, and the effects of advertising on society. By examining these aspects through an anthropological lens, it becomes possible to gain a holistic view of the historical developments in advertising and the emergence of professional agencies in the late 1800s. Additionally, Lewis points out the ethical missteps of early anthropologists who exploited their study subjects, signifying the importance of moral considerations in research.
Anthropologists today extend their studies to the production of visual media and analyse its impact on personal and cultural representation, as seen in the examination of visual anthropologists' work. Moreover, Scott's application of psychology to advertising in the early 20th century reveals an interdisciplinary approach, integrating psychological principles into business practices. This further demonstrates the expanding domain of anthropological research in context to marketing and advertising.
