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.
Either you upgraded from a plan without regional sports to one that does (probably with a bunch of other channels you may have wanted) or your previous plan didn't itemize the RSN fee. This is the standard cable/satellite TV model. You pay for a bunch of channels you don't want in order to get the few you do.
