CBC Television has aired National Hockey League (NHL) broadcasts under the Hockey Night in Canada brand that is primarily associated with its Saturday night NHL broadcasts throughout its history in various platforms.

CNR Radio or CN Radio was the first national radio network in North America. It was developed, owned and operated by the Canadian National Railway between 1923 and 1932 to provide en route entertainment and information for its train passengers. As broadcasts could be received by anyone living in the coverage area of station transmitters, the network provided radio programming to Canadians from the Pacific coast to the Atlantic coast.
