Another thought.
Production companies. The ones that produce shows for the networks. There's an "in". Do a search for television and video production companies as well. Start getting religious about jotting down info when you watch shows on A&E, TLC, PBS, etc...and note at the end of the credits who the production companies are, and find their contact info on the net as well, call them, and ask the same questions I mentioned in the previous thread.

It's all detective work really, and is time consuming, and without any friends in the biz to open doors, these are the routes to go. You'll develop a savvy way to "market" yourself as you go through these processes.
