Although not specifically directed at the TV biz, this article is loaded with tips for corporate creatives in all fields:

Tell me if this has ever happened to you: A well-known person in your field loses their job with impressive company X. Deep, deep inside you feel a vague sense of guilty satisfaction. They weren’t that talented anyway, you tell yourself. This will clear room for more up-and-coming talent, you say.But then weeks later when you’ve already mentally moved on, you read that well-known person has landed on their feet, yet again, with a new job at impressive company Y. No schadenfreude for you. So what is that well-known person’s secret? It’s not (always) talent. No, the thing that keeps creative people employed and in full control of their destiny, isn’t some hidden genius. It is the ability to build and serve an audience. Cynically, it’s much harder to quietly let someone go if their 4,000 Twitter followers will hear about it. But practically for those of us whose who operate behind the scenes or aren’t the “face” of our department or company, an audience is the best job insurance possible.
Consider the plight of the person hiring creative talent. Or the person hiring anyone, really. They have a marketing campaign for a client meant to build customers. Or maybe they are responsible for a team that does not have a ton of headcount to work with. While the job market is risky, those doing the hiring are risk averse—VERY risk averse.
