The radio is an innovation that fundamentally transformed the landscape of communication and entertainment worldwide. Its invention is credited to an Italian electrical engineer, Guglielmo Marconi.
The invention of radio communication was preceded by many decades of establishing theoretical underpinnings, discovery and experimental investigation of radio waves, and engineering and technical developments related to their transmission and detection.
Although its translation of the 1906 Berlin Convention used the terms wireless telegraph and wireless telegram, by 1912 it began to promote the use of radio instead. The term started to become preferred by the general public in the 1920s with the introduction of broadcasting.

Learn more about the history, development, and principles of radio technology in this article.
In the early 1900s, the development of radio was hampered by the lack of an efficient detector of electromagnetic radiation. It was De Forest who provided that detector. His invention made it possible to amplify the radio frequency signal picked up by antennae.
Already more than 100 years old, radio is still a powerful force in American life. According to a 1998 Arbitron report, over 95 percent of Americans listen to radio at least once a week.
