Radio is one of the easiest types of media to use, providing listeners with music and real-time news. The radio has played an important part in society throughout the 20th century.
Unlike other media types, such as newspapers, radio stations have the ability to become a reliable source of information in areas where information is scarce. People from all around the world can search the airwaves for reliable sources of information even when phone lines are cut and the Internet is blocked. Radio also plays an important role in war zones. Small communities benefit from local radio stations that provide news about local issues that would otherwise not make national headlines.
