I faintly remember these two instances from sixties television:
Tony Franciosa threatening Jill St.John with a spanking if she repeats some transgression
An instance on the Bob Hope Show (I think he hosted a weekly drama show) where a young woman said at the end of an episode: "he spanked me, I haven't been spanked since I was a little girl".
I would appreciate it if anyone can fill in the details.
