The original Disney-produced TV series Zorro (starring Guy Williams) ran from 1957-59, but a decade after its debut on ABC it still had life in reruns. This ad for the show ran in 1967 and shows us that it was airing on WKYT-TV (channel 27) out of Lexington, Kentucky. The station started out as a CBS affiliate, switched to ABC in 1958, and moved back to CBS in 1968.
I'm sure the context for this ad from the May 4-10 edition of TV Guide's Atlanta edition makes this seem perfectly reasonable. But because I can't resist a good sight gag, let's just enjoy this ad for WWLA's Cracker baseball broadcasts as is. OK, in the spirit of fairness I will mention that Crackers was the name of Atlanta's minor league baseball team, and they were part of the rather successful Southern Association. The league disbanded in 1961, which left Atlanta without a baseball team until the Braves moved from Milwaukee in 1966. As for WLWA-TV (now WXIA) having a sports broadcaster named Bob Boring, I'm not gonna kill that joke with facts.
