Final answer:
The statement that record sales skyrocketed during the Great Depression due to the proliferation of radio is false. Economic hardship during that time meant less disposable income for non-essential items like records.
Step-by-step explanation:
During the Great Depression, it is false to say that record sales skyrocketed due to the proliferation of radio. In fact, the Great Depression was a time of significant economic hardship where disposable income was scarce and luxuries such as record purchases were often foregone in favor of basic necessities. While radio did become a popular form of entertainment, and President Franklin D. Roosevelt used it for his "fireside chats" to reach the American public, it did not lead to a surge in record sales during this period. The market revolution indeed caused many social and economic changes in the United States, and the Great Depression had a profound impact on consumer behavior and production patterns. Post-World War II, there was indeed a boom in consumer spending and production, but this is not to be confused with the economic conditions of the Great Depression era.
