From Wikipedia, the free encyclopedia. In the United States and Canada, a regional sports network (RSN) is a cable television channel (many of which are also distributed on direct broadcast satellite services) that presents sports programming to a local market or geographical region.
Other distributors have followed DirecTVâs lead with the RSN charge â Verizonâs FiOS TV began implementing a $2.42 monthly charge for RSNs in California, Texas and Florida in February, with plans to expand to its remaining sates in March. In Maryland and Virginia, the surcharge will take effect in April.
