Temporary Entertainment Positions: One of the fastest ways to get the experience you need is to sign up with a "temp agency." Temp agencies will place you in a wide variety of positions within the entertainment industry. Most of these positions are administrative positions such as working as someone's assistant for a few days or weeks. At first glance these jobs might not seem all that glamorous. But it's often the perfect way to get yourself on a studio lot.
You'll meet a number of potentially influential people, and you'll be in the perfect position to find out what else might be available that matches a bit more with your career goals. Make sure that when you seek out a temp agency, you find out whether or not they specialize in working with entertainment and/or media companies. You can find out which temp agencies each major studio or network uses by contacting their human resources departments and simply asking the first person that picks up the phone.
Internships in Entertainment: Most of the major networks and studios offer up a wide variety of internship programs. You don't necessarily need to be in college to take advantage of them either. These programs are in a wide variety of fields from writing and directing to programming and development. If you are a minority then you might look to see what minority specific programs each company might offer. You might be pleasantly surprised by the number of opportunities that you can qualify for. To find out about these programs, simply visit the various corporate websites and under their "jobs" sections you will find a list of available internship programs.
Volunteering: One of the easiest ways to get a bit of experience is to offer to work for free. Almost everyone in the entertainment biz could use an extra pair of hands and if you can afford to forego a paycheck for a bit you'll be greatly surprised by what you can find. For example, if you live in Los Angeles or New York chances are you have driven past a few movie sets. Next time, park your car and walk up to someone on the set and ask if there are any departments that they know of that could use a little free labor. From the camera department to the make up department most movie sets are often shorthanded and more than likely, you'll sign a waiver and be working the same day.
