A few years ago, SyFy's viewership flattened, and not surprisingly: the channel had come to stand for robots, UFOs, and other affectations of 28-year-old men living in their parents' basements. But to me, the genre was less about alien invasions and more about the human imagination. I rebranded it accordingly. Today it's one of the most profitable businesses in NBCU's slithering, hydra-headed portfolio.
