Life is finally imitating art on the Cincinnati dial. More than 40 years after the fictional WKRP turned “Livin’ on the Air in Cincinnati” into a pop-culture catchphrase, the famous call letters are landing on a real Tri-State radio station. Local 12 (WKRC) reports the move pairs the beloved sitcom name with a retro playlist, the kind of nostalgic full-circle moment that’s catnip for anyone who grew up on the show. For fans who’ve spent decades quoting the bumbling crew at the fictional station, hearing those four letters announced for real on the airwaves is the payoff of a long-running inside joke. It’s a small story with a big grin attached.
