The Sportsnet license comprises four 24-hour programming services; Sportsnet was originally licensed by the Canadian Radio-television and Telecommunications Commission (CRTC) as a category A service, operating as a group of regional sports networks offering programming tailored to each feed's region (in contrast to TSN, which was licensed at the time to operate as a national sports service, and could only offer limited regional opt-outs). Since 2011, the service has operated under deregulated category C licensing, which allows Sportsnet to operate multiple feeds with no restrictions on alternate programming. 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).
