The ala carte cable\satellite thing is a fantasy that some have that is never coming.
Not sure if you're living in a cave, but cable/satellite subs are decreasing now and will decrease at a higher rate as more CATV/SAT customers migrate to Internet TV options (which will significantly improve as technology evolves). In response, there are a couple of options for CATV/SAT providers. Decrease their packaged pricing or provide more ala carte options. The result is that niche networks like BTN are going to face downward pressure on CATV/SAT subs. Even Jim Delaney would tell you that.
