Final answer:
The 1920's introduced groundbreaking technology like Ford's Model T and advancements in aviation, transforming transportation and creating a national consumer market. Advertising, pro-business policies, and commercial radio characterized the business changes, despite the subsequent Great Depression.
Step-by-step explanation:
The 1920's was a transformative decade for technology and business. The period was marked by significant technological advancements, particularly in the realm of transportation. One of the most groundbreaking innovations was Henry Ford's Model T, a vehicle which revolutionized the automotive industry by making car ownership accessible to the average American. This era also saw the rise of the aviation industry, progressing from producing a few hundred to 5,000 airplanes annually by the end of the decade.
The 1920's were characterized by a shift from local economic control to a national consumer market. Advertising and mass distribution of consumer goods led to uniformity in various aspects of American life, ranging from fashion to entertainment. The emergence of commercial radio networks revolutionized communication, making radio programs a staple in American households. Accompanying the economic expansion was a pro-business government, with leaders like Calvin Coolidge embodying the philosophy that the primary concern of the nation was business.
Despite these advancements, the prosperity of the 1920s masked underlying economic fragility, which unfortunately culminated in the onset of the Great Depression. However, the era remains a significant point in history for demonstrating how technology and business can profoundly influence society and culture.
