From what little I know, it was the rise of regional cable TV in the states in the late 70s, that needed a lot of cheap filler programmes that kept Star Trek: TOS going*. Having 100+ shows instead of 70+ I don't think would make a whole lot of difference to how it was view**. That said we don't know what the episode would have been. If they were all stinkers, then it would have gone down as a turkey. If there were a few more gems.
* It was Star Wars that started the movie franchise and their success made TNG and the rest possible.
** The horror channel in the UK has been showing TOS every day and has run through all of DS9 and most of Voy, so I think the love is still there.
