How might the economy of the 1920s have a different without the advertising industry?

Without the advertising industry, the economy of the 1920s would likely have experienced slower consumer growth and less widespread adoption of new products. Advertising played a crucial role in stimulating demand and shaping consumer culture, encouraging people to purchase goods like automobiles and household appliances. Without these persuasive marketing strategies, the economic boom fueled by consumer spending might have been less pronounced, potentially leading to a more modest economic expansion and delaying the onset of the Great Depression. Overall, the vibrancy and dynamism of the 1920s economy would have been significantly diminished.
