 For example, to protect TSN, The Score (now Sportsnet 360) was specifically licensed to serve as a sports news service (instead of a mainstream, national sports network), and was limited in the amount of live programming it could air.However, following inquiries into the matter, the CRTC announced in 2009 that it would begin to allow leeway in certain broader categories, such as news and sports.To prevent them from airing programming from outside their designated format, the CRTC employed a system of "program categories", specifying how much of a service's weekly programming could be devoted to specific genres and classes of programming.
