By their command.

In keeping with their Stargate marketing strategy, I presume, Sci-Fi announces a new prequel-series to Battlestar: Galactica, Caprica, set 50 years before BSG. “Following the lives of two families, the Graystones and the Adamas (the family of William Adama, who will one day become the commander of the ‘Battlestar Galactica’) ‘Caprica’ weaves corporate intrigue, techno-action and sexual politics into television’s first science fiction family saga.” Um, ok. I think I’d rather just see BSG stay good through Season 3.
