CINCINNATI (AP) – In a Nov. 29 story about a television station promoting its new digital signal, The Associated Press erroneously reported that station WBQC changed its call letters to WKRP. The station refers to itself as WKRP, reminiscent of the 1970s hit television show “WKRP in Cincinnati,” and changed its trademark to WKRP Cincinnati but did not change its call letters, said Elliott Block, general manager.
