This isn't radio, but on TV, the Hallmark channel, along with numerous other "family friendly" channels, began airing 24/7 Christmas movies around November 1, and only stopped last night at midnight.
The music I can handle (I can tune in or out depending on my mood), but movies too?!
Incidentally, even though it's not in market, I'm pretty sure I heard Grandma Got Run Over on either KYNO or KVMI.
