Unlike most other cable networks, CSN Philadelphia is only distributed via microwave and fiber optics. The infrastructure Comcast uses for this was left over from the now defunct PRISM Network. Since its programming is not transmitted by satellite, Comcast is able to avoid an FCC regulation that requires most television channels to be offered to direct broadcast satellite companies. Thus, DBS customers in the Philadelphia region do not get access to the network or any of the local teams' games. However, cable companies other than Comcast within the designated CSN Philadelphia market do have access to the channel. In December 2006, Comcast even made a deal to place CSN Philadelphia on Verizon's competing FiOS systems.[2] All of the other members of Comcast SportsNet are available to DBS subscribers, with the exception of CSN Northwest (however this is only because DirecTV and Dish Network have not been able to reach a carriage agreement with Comcast).
