Radio allows you to target your message to specific groups. Some stations are after the widest possible audience, but many point to niche markets, such as adolescents, sports fans, news junkies, political conservatives, university students, educated people, or fans of any kind of music. Advertising a smaller station could cost more individual listener, but have a much greater chance of reaching a demographic target.

Radio advertising involves :- Free commercial time, RJ mentions, Sponsorship Tags, Testimonials, Interview.
