From My Experience A lot more goes into radio broadcasting than you think… What it entails: Having a topic ready Maintaining a conversational tone Having your playlist ready Learning the switch board Microphone Checks Knowing the different laws and principles And much, much more….

What to Expect From Radio Broadcasting in the Future… Company ownership and investments in technology. The FCC estimates there will be nearly 800 million radios in US households, private and commercial vehicles, and commercial establishments. Radio programming will shift away from music and back to its roots as a program formatted medium. The programming changes will result in fewer job opportunities in programming and on-air operation, in turn the effort to increase revenue will result in the effort to hire more sales personnel.
