The first radio came out in 1879. The first radios were bulky, noisy, and had poor reception. After time the radio began to improve.
Once radio signals could be transmitted and received with improved speed around 1920, the idea of public radio began to take hold in America. The first public radio broadcasting station opened in Pittsburgh, 1922. It was an instant success; listeners would sit around the radio listening to everything that was broadcasted. As a result, many more radio stations popped up during the 20s, at day and night.
Radio provided a cheap, uncomplex and convenient way of transmitting information and ideas. The first broadcasts consisted of primarily news and world affairs. Today, people play songs, reports, news, sports, speeches, and other information.
The radio was certainly one of the most important inventions of the 1920s, not because it brought a whole new way for people to communicate and interact together, but because it brought the nation together.
