sentences:  Since Windsor is considered part of one large American media market (Detroit) and close to two others (Cleveland and Toledo), the city's media outlets (radio and television stations, and newspaper) have a special status designated by the Canadian Radio-television and Telecommunications Commission, exempting them from many of the Canadian content ("CanCon") requirements that most other broadcasters in Canada are legally required to follow.These CanCon requirements, mandating that a minimum of 35% of the broadcast material of a station must be of Canadian artists, actors, or shows in/about Canada, have been blamed in part for the decline of the popular Windsor radio station, CKLW, a 50,000-watt AM radio station that in the late 1960s, prior to the advent of CanCon, had been the number one radio station not only in Detroit and Windsor, but also in the Toledo and Cleveland markets.Windsor has also been exempt from the CRTC's concentration of media ownership rules.
