A radio broadcast is a method of transmitting audio content to a wide audience using radio waves. This content can include music, news, talk shows, and other forms of entertainment. Radio stations operate on specific frequencies, allowing listeners to tune in using a radio receiver. The history of radio broadcasting began in the early 20th century, with pioneers like Guglielmo Marconi playing a significant role in its development. Today, radio broadcasts can be accessed through traditional AM and FM frequencies, as well as digital platforms and online streaming services, making it widely available to listeners around the world.
