You apply for a job, like in any other company. You may start in the mail room, but may be you can get an "assistant" job instantly, that's usually either the door-opener or a dead-end. Look for the ads. You may start as an intern in some agency/studio, work for free first, but it gives you experience which is GOOD for your resume. As far as I know a degree is a must.
So, a degree, internship, work in some agency/channel/magazine and the you'll be able to get similar jobs at FOX, Paramount, etc.
