In 1923, Westinghouse Electric created a national system of radio broadcast through the use of short wave relays. In November, 1924, its international broadcast of Calvin Coolidge's landslide victory in the 1924 presidential election enabled Coolidge's father to hear the news in his Vermont farmhouse, an event documented by this news photograph.
