Once upon a time, SciFi - or whatever they're called now - brought us the awesomeness that was Battlestar Galactica. While watching the series, especially various webisodes, fans were subjected to many ads for the network's other offerings (Wyvern stands out). This elicited a lot of complains and snickering on the fan board I was on. But it was pointed out, this is how the network can afford to make our wonderful Battlestar. I believe Ron Moore said much the same thing in his podcast. They knowingly produce a lot of drek, which they use to fund the occasional gem when something edgier presents itself.
