Who was the first President to use mass media as a significant tool?

Franklin D. Roosevelt was the first President to effectively harness mass media as a significant tool in communicating with the public. His use of radio, particularly through his "fireside chats," revolutionized the way presidents could engage with citizens directly. These informal broadcasts allowed Roosevelt to discuss his policies, explain complex issues related to the Great Depression, and reassure the American public, making them feel more connected to the presidency.

Roosevelt's adept use of mass media marked a turning point in political communication, as he understood the importance of reaching the public through new forms of media. His presidency coincided with the rise of radio as a dominant medium, and he capitalized on this to shape public opinion and foster trust. This strategic approach to communication laid the groundwork for how future presidents would use mass media, including television and other forms of communication, to influence the electorate.
