Radio had a major effect on politics, starting way back at the invention of the radio at the dawn of last century all the way through to the present. The radio enabled presidents like Franklin D. Roosevelt to address the entire nation (at least those that were tuning in) with weekly radio addresses, though it was Calvin Coolidge to deliver the first address to Congress over the airwaves.

Roosevelt created quite the tradition; weekly radio addresses are continued today, though they have undergone technological advances, integrating podcasts and YouTube! Reagan, George W. Bush, and Barack Obama have all produced some form of weekly radio addresses.
