Sportsnet (formerly known as CTV Sportsnet and Rogers Sportsnet) is a Canadian English-language Category C sports specialty channel owned by Rogers Communications.
Although licensed by the Canadian Radio-television and Telecommunications Commission (CRTC) as a single national service, for all intents and purposes it is equivalent to a collection of four regional sports networks, each simulcast in both standard definition and high definition, and each covering a different region of Canada. In each region, only the local Sportsnet channel is available on analogue cable, but all four channels are available nationally via digital cable (subject to blackouts for some out-of-market teams).
The Sportsnet brand has since been extended beyond the original regional channels, now encompassing the national digital channel Sportsnet One (and its associated part-time companion channels), the soccer/rugby premium channel Sportsnet World, Sportsnet Radio stations in Toronto and Calgary, and Sportsnet Magazine.
With these brand extensions, Rogers now generally uses "Sportsnet" (by itself) to denote its sports media properties as a whole, and on-air promotions for programs being carried nationally by these four regional feeds often list all four channels separately, or refer to the "Sportsnet regional channels", to avoid any ambiguity. However, standalone mentions of "Sportsnet" in reference to a specific channel can still generally be assumed to be referring to the four regional channels (or the specific regional channel available locally on analogue cable).
