The network(s) carrying the games charge so much to the cable provider to carry their channel in their packages. A large draw of many networks which broadcast baseball is the exclusive rights to those games. Right now, if you live in Chicago, the only way you get non-WGN/WCIU games is to subscribe to a cable package which includes Comcast Sportsnet. If you have the option of buying mlb.tv to get your Cubs fix, cable subscriptions go down, CSN cannot charge as much because they're not drawing in subscribers, and if CSN can't charge as much, they aren't making as much on the Cubs, thus they won't pay out the same for their TV contract. ETA: shut up TT I get that for in-market, but what about for areas that don't have access to cable providers who carry said networks? Wouldn't they stand to make MORE money if they didn't black out those weird blackout zones with no access to baseball?
