I think that if you want to be competitive in the industry, you should go to college. I started my broadcasting career in a local market and eventually worked for a national network. Every broadcast facility I worked at got demos and/or resumes from college grads who were willing to work for free to get their foot in the door. Some got production internships, and others got in by taking whatever job was available (answering phones, doing grunt work in the traffic department, etc.).
Even the kids with 2-year degrees had at least a year of production experience in college and understood important production terms, so the producers didn’t have to waste time and money they didn’t have on training. It’s more difficult for people who want to be on-camera personalities (talent). A game show has a single on air host, but a crew that includes a producer, director, 2-3 camera people, makeup, lighting, sound, and editing staff. There are far more crew jobs available than there are talent jobs, and even those are highly competitive. I wouldn’t consider a career in broadcasting without considering college first.
