Watch other television personalities, whether they are game show hosts, news reporters or weathermen. Notice their onscreen demeanor, such as how they speak and the way they dress.
Practice memorizing storylines, facts, figures and dates.
Decide on a field of specialization. Read up and become an expert in that area. For example, if you wish to be a movie host, become familiar with the world of motion pictures. Research especially the ones that made history.
Take courses in communications and journalism. Such classes are available at two- and four-year colleges.
Seek internships, whether paid or not. Call your local TV stations to see if any of them participate in programs with your college. Also search your college intranet for such internships. Apply for them by preparing a resume and cover letter. Include on the resume the classes you've taken thus far and any communication-related volunteer work you've done, or work on a high school TV station.
Observe what takes place behind the scenes of a television program during your internship. Take note of interactions between on-air personalities and their producers and directors. Watch what the personalities do right, as well as the mistakes they make, both in front of the camera and behind the scenes.
Apply for volunteer jobs at the local community access channels. Treat this position as a paid opportunity. Report for duty on time, and do your best work. Take your relationships with any producers and directors seriously as you will need them for references later.
Cut a videotape of yourself. Ensure that it is of professional quality. Present the day's current events speaking into a microphone and looking into a video camera. Behave as if you were in front of a camera at a professional television station. Dress in your best professional attire. Exude a sense of self-confidence in front of the camera. Look directly into the camera as that is your only means of making direct eye contact with your viewers.
Apply around the country -- and the world -- for employment in your field. Upload a copy of your videotape in your email to employers, along with your resume and cover letter as email attachments to various television stations. Prepare for any auditions by continuing to practice your presence in front of the camera.
