I remember back in the 1970's KIRO TV which is our CBS affiliate in Seattle would always make a disclaimer when they make a station identification before going to CBS programming. They would show the CBS eye logo with "7", under the logo it would say "KIRO TV SEATTLE", and in the bottom it would say "A CBS AFFILIATE". Was that a common practice for CBS to make that disclaimer in those days? And did both ABC and NBC affiliates did the same practice too as well? I don't remember seeing this with KOMO and KING also in Seattle.
