I think Westerns were relatively cheap to produce, at the time. Lots of open spaces to film in not far from Hollywood, lots of horses still easily obtainable, cheap costumes, not much in the way of special effects.

Notable westerns were shot in Spain ( Once upon in the west comes to mind ).

See also spaghetti westerns. They were low cost but obviously if you crank out many hundred films of a genre there’s obviously a demand for them.

Which comes back to my original point. After all those movies there was still a demand. Where was that demand originating from?
