Battlestar Galactica was a Sky co-production, they're reasonably new to commissioning original shows, but make a lot of money off of genre TV imports. TBH, despite the Murdoch association, I think Sky might be better than the snobby Beeb at genre.

OTOH, the Beeb are doing their own show, not got a link to hand though, was in a Times article I read in t'pub.
