What is the Regional Sports Network (RSN) Fee and why am I getting charged for it?

Many DIRECTV customers in your area have requested these channels so they can watch all the games from their local teams, so we include them as part of our base programming packages. Regional Sports Network fees of up to $8.49 apply in certain markets. Regional Sports Network Fees are updated biannually based on the presence of Regional Sports Networks and/or Collegiate-In-Market programming in applicable ZIP codes.
