Final answer:
Pittsburgh is where the news of Warren G. Harding's landslide victory in the 1920 presidential election was first broadcasted over public radio, signaling an era that desired normalcy and less governmental interference.
Step-by-step explanation:
In the context of radio's impact on communication and politics, Pittsburgh is recognized as the city where the news of Warren G. Harding's landslide victory in the 1920 presidential election was first broadcast over public radio. With an overpowering Electoral College score of 404 to 127 and 60 percent of the popular vote, Harding's win was a clear call from the American public for a return to normalcy and an anticipation for what would become known as the Jazz Age. It is also worth noting that although Harding was known for utilizing radio broadcasts, it was President Franklin D. Roosevelt who became famously associated with the medium through his 'fireside chats' that gave Americans a sense of direct communication with their leader during tumultuous times.
