Um... costs really vary. A lot depends on the mode of production, the development budget, etc.

Episodic costs on Gargoyles averaged about $450K per episode, at least for the first 65 episodes. (I have no idea what the final budget was for Goliath Chronicles, but I imagine it was considerably less.) And those per episode costs do NOT include development costs, marketing costs, etc. So making a series is a VERY expensive prospect, which is why we need/put up with studios, networks and the like.
