Not surprising...it's only a year and a half old, and it comes as part of DirecTV's basic package but Comcast doesn't offer it at all. Pivot's programming has been mostly repeats of documentaries and cult TV shows (Buffy, Farscape, Veronica Mars, Friday Night Lights). Its only original programming has been low-budget stuff like talk shows, so it's remarkable that Pivot should come up with something as expensive and ambitious (and GOOD) as Fortitude.
