I am, naturally a Jays fan (I know, I know...don't go there),but before there were Jays (or Expos for that matter), I was, and still am a Pirates fan and Dad still loves his Cubbies.
I also always thought the advent of so many channels and packages helped bring about the demise of Trek. I always thought the channel dedicated to science fiction would be a natural fit, but I guess it is too niche a market for the kind of audience numbers that are needed to keep something on the air.
