How did consumerism change in the 1920s and why?

In the 1920s, consumerism underwent a significant transformation driven by economic prosperity, technological advancements, and cultural shifts. The rise of mass production techniques, such as the assembly line, made goods like automobiles and household appliances more affordable and accessible. Advertising became more sophisticated, promoting a culture of consumption and encouraging individuals to purchase not just necessities but also luxury items. This era marked a shift towards a consumer-oriented society, where personal identity and social status were increasingly defined by material possessions.
