YO DJ!1INTRODUCTIONRadio has evolved greatly since its birth in the late 1800’s. Although it was growing and evolving since birth, the greatest period of change occurred after World War II to present day. From privatized AM broadcasting, to commercial FM radio to the current crop of internet & satellite radio stations, technological advancements have changed the way we use radio in our daily lives. The commercialization of radio significantly changed the entire radio/broadcast medium. In the early days of radio, companies did not believe that broadcasting entertainment and news programs could generate revenue and become profitable. Radio’s power to reach the masses over far distances has been it’s greatest strength. Radio opened the door for global-realtime communication of ideas and messages.

After WWII a technological innovation in Frequency Modulation, also known as FM, produced a clearer, static free signal. Although FM radio was clearer and could transmit music better, it struggled to with AM radio. By this time television had also begun to enter the marketplace, which began to sway advertisers and viewers/listeners attention. In 1945 the Federal Communication Commission or FCC restricted FM toward the higher end of the dial since FM and Television had previously occupied some of the same frequencies on the electromagnetic spectrum.The most enduring cultural legacy of radio is the music it presented. Prior to radio, the piano sheets and word-of-mouth were the channels through which popular songs made its course.
