For baseball at least, the same points are valid for each area's RSN (regional sports network). MASN (Maryland / DC / VA area) gets something like $8-12 per subscriber. YES (NY Yankees network) I'm sure is able to charge even more.
This has allowed MLB teams to spend a great deal of money in the past 5-10 years as teams have signed ever-more-lucrative television rights deals with FoxSports and others. If non-cable media packages are luring more and more cable subscribers (HBO, Hulu+, SlingTV, Netflix, etc) the pool of non-sports watching people subsidizing these networks shrinks - this will force either prices to rise for actual sports watching customers, or it'll lower revenues for teams.
Rumor has it that MLB has been trying to push the RSNs to accept universal MLB.tv access for all regional markets, this at least makes the costs explicit - $100-140/season for each subscriber.
There is more synergy there though. RSNs show more games with the team you like. It only makes sense to charge more and the fans are more than willing to typically pay it.
