What is it that has always attracted the BBC to Yorkshire, like a pile of iron filings to a magnet?

I keep remembering series of old, like I Didn’t Know you Cared, Last of the Summer Wine, Dinner Ladies and that other one set in a police station (Rosie? The Thin Blue Line? Both?)

Now, on a friend’s recommendation, I’ve gone back and watched all of Happy Valley which was awesome and I’m now on Last Tango in Halifax which is equally gripping. There’s something about the vein of gentle humour that’s runs through them all that is appealing.

So why Yorkshire, and are there any I’ve missed?
