It's the sport that keeps me hooked in.
TV shows, I d/l anyway. Although the lead-time between US airings and Sky airings are a lot narrower than terrestrial, it's still too much for me.
I'm not entirely sure which I prefer though... When they don't show it till January, at least they don't have all those gaps in between episodes like the American's have. But If they're showing it same week, it means you don't have to wait, or waste bandwidth downloading it.
I believe BBC 2 are planning on showing Heroes season 3 right after the American broadcasts later this year, so it looks like terrestrial channels are cottoning on to the idea.
