In the United States of America, a Regional Sports Network, or RSN, is a cable television station that presents sports programming to a local market. The most important programming on an RSN consists of live broadcasts of professional and college sporting events, as those games generate an overwhelming percentage of an RSN's advertising income. During the rest of the day, these stations show other sports and recreation programming. These channels are often the source content for out-of-market packages. In Canada, Rogers Sportsnet operates four regional sports networks.
