What was the importance of advertising for American culture in the 1920s?

Advertising in the 1920s was crucial to American culture as it reflected and fueled the consumerism of the decade. It helped shape public perceptions and desires, promoting new products and lifestyles that emphasized modernity and individualism. The rise of mass media, particularly radio and print, allowed advertisers to reach broader audiences, transforming shopping into a cultural phenomenon. This era’s advertising not only influenced consumer habits but also played a significant role in defining social norms and aspirations in post-World War I America.
