The consistency of that one brand they created probably helped a ton. You guys have a broad spectrum of good shows, but it could be that the shotgun approach has diluted the brand if in no other way than that it has hurt a consistent release schedule for everything. I wonder too if show length, and therefore size-on-disc of each episode is a thing? Nightvale is 20-30 minutes each, bi-weekly, so it has a pretty small on-device footprint. I personally like longer episodes, just kind of thinking out loud about some of the possible variables.
