Radio

Radio is a part of media that is used to broadcast sound through sending radio waves to transmitters.

Alongside television, radio is another huge part of media. Since there are many genres in radio, depending on the style of music the stations broadcast, radio possesses a large audience. Before television, radio was the major media for broadcasting. Even nowadays, radio still is the major media people uses to gain information or get entertained. Also, it is easy to target specific group of audiences. For example, people in 50's are not likely to listen to hip-hop radio, while people in teens are not likely to listen to country music.

Yet, there are some downsides of radio. When listening radio, people do not always pay close attention to it. Therefore, radio stations might not be able to pass on all the messages they were planning to pass. Furthermore, people cannot refer back if they missed something.
