I wonder how losing the Cubs would affect WGN in the cable marketplace. I've been told by cable execs in places where I've lived (which didn't carry WGN, I always seem to end up in such places) that they don't offer WGN because of all the baseball. On the other hand, I have to believe that some cable systems carry WGN because of the baseball. I don't know how many, if any, markets black out WGN baseball.
What WGN has determined they will spend on baseball has to be based on market research showing them they will gain.
In theory, as it would have no effect on me, I would love to see the Cubs limited to their own network. I wouldn't even mind if Cubs executives decided to embrace the pay-per-view future.
