FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity-more accurate reproduction of the original program sound-than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies.

Radio stations are essential in supporting local events, promoting local businesses, and rallying behind charitable causes. Moreover, radio serves as a vital source of local news, weather updates, and emergency broadcasts, providing real-time information to listeners when it matters the most.
