(As a side note, the CBC station in Windsor, ON generally was on the other side of exclusivity deals, as they did not carry U.S. network programs that were part of the CBC schedule. Interestingly, that station was the mirror image of KVOS for many years, and operated as a de facto independent station as CKLW-TV serving Detroit until the mid-70s. They weren't a full independent station since they did carry the CBC's schedule of Canadian-produced programming, though...just as KVOS carried some CBS programs. That ended when the Canadian government forced the sale of the station and it came under direct CBC ownership as CBET.)
