They a Revolutionary War aestetic, so the blackout must intelligently and selectively shut down any tech that interferes with that.
I haven't seen the show (don't have cable), but I have to ask:

If it's another "technology sucks" diatribe, like the Emberverse and nuDayEarthStoodStill, I'm afraid they're not gonna have many takers...
