Formal training is usually necessary to develop one's talents.
The video taped audition that presents samples of the applicant's delivery, style, and appearance often is the most important factor in hiring. A liberal arts education provides an excellent background for an announcer, and many of the universities offer courses of study in the broadcasting field. They also may advance by hosting a regular program as a disc jockey, sportscaster, or other specialist. Announcers often work within tight schedule constraints which can be physically and mentally stressful. Openings in this relatively small field will arise from the need to replace those who transfer to other kinds of work or leave the labor force.
