The fireside chats were a series of thirty evening radio speeches given by United States President Franklin D. Roosevelt between 1933 and 1944.
Origin of radio address
According to Roosevelt’s principal speechwriter Judge Samuel Rosenman, he first used "fireside chats" in 1929 during his first term as Governor of New York. Roosevelt faced a conservative Republican legislature so during each legislative session he would occasionally address the citizens of New York directly in the camelback room. He appealed to them for help getting his agenda passed. Letters would pour in following each of these "chats," which helped pressure legislators to pass measures Roosevelt had proposed. He began making the informal addresses as President on March 12, 1933, during the Great Depression.
Rhetorical Manner
Sometimes beginning his talks with "Good evening, friends", Roosevelt urged listeners to have faith in the banks and to support his New Deal measures. The "fireside chats" were considered enormously successful and attracted more listeners than the most popular radio shows during the "Golden Age of Radio." Roosevelt continued his broadcasts into the 1940s, as Americans turned their attention to World War II.
