Radio is the use of radio waves is to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width

The ultimate goal of the media is to inform, educate and entertain, and in most cases to bring to light the policies of the government. The radio is the cheapest media type and as such has a wide media coverage. With the trying time in Nigeria it is the sole responsibility of any radio establishment to gear up as patriotic Nigerians and disseminate information through effective programmes. Like it or not, information is key and radio serves as a life line during emergencies and help empower people in devastated communities just as the broadcast commission urged. finally an effective broadcaster should posses the following qualities
1. Good posture, To improve your on-radio voice and develop a persona, School Report recommends you “find an alert and comfortable position that signals to your body you are in work mode.”
2. Be natural, encourages broadcasters to just be themselves. Personalities should not be forced—and, they should be developed over time
3. Remember the Mic, treating the microphone “as a human ear.” Speaking directly into the microphone can make it easier for the audience to hear you (which is the most important part of broadcasting).
