Yes. It's noticeable that the Dark Shadows remake series of the same era was regularly pre-empted on NBC because of the Gulf War and only lasted 12 episodes as a result (annoying, because it was a series that had potential after a shaky start!)
I agree Fox might have been a better home for Twin Peaks in some ways, but I wonder how the series would have fared in terms of budget. I seem to recall Fox's budgets were quite tight and it didn't have the national coverage of the other networks at that point. The series would likely have had to be scaled back and I imagine, like The X-Files, filming would have had to have been done entirely in Canada, which would have impacted casting, choice of producers, directors, crew and so on.
As has been said elsewhere by a couple of us in other discussions, Twin Peaks was never realistically going to manage being a 22-episodes-a-year series lasting for at least seven seasons. We'd be looking at at least 110 more episodes after season 2. Season one - being a mid-season replacement - is, in effect, an eight-part movie - and was a hit because of that tightly focused small number of episodes - which is followed by effectively a nine-part sequel, then a rather flabby, shapeless, directionless weekly show for the rest of season two. I'm afraid most of the 13 final episodes of season two is what anything further would likely have looked like.
So, regardless of network, I think the series would have struggled in the long term. If it could have been eight episodes a year, I imagine it would have been amazing: imagine ending season two on episode 7 (the first part of the season being double length) with Maddy's murder. Then season three could have been a Fire Walk With Me flashback season, before returning to the present or future for season four, leading to Cooper's entrapment in the Black Lodge and season five about his escape...
So, yes, Twin Peaks might have found a home on Fox, but imagine the series being much scaled back in terms of locations and characters and limits on how much time many production team members and actors could spend in Canada. The X-Files managed very well in Canada, but it was reliant on Canadian - and Canada-based - producers, directors, crew members and actors. I wonder how much of Twin Peaks David Lynch would have been allowed to direct. Would Tina Rathborne, Caleb Deschanel, Lesli Linka-Glatter, Mark Frost or Diane Keaton been allowed to direct episodes? The Canadian-filmed 1980s third season of The Twilight Zone had the situation where the production team was based in the USA and couldn't go on location, meaning they were writing scripts and organising shoots from a thousand miles away.
In the end, I think Twin Peaks was a series that was lucky to last as long as it did. It had 16 really great episodes, one rushed episode to end the murder storyline, 12 very shaky weekly episodes and a headscratchingly effed-up masterpiece of insanity that still makes me smile to think managed to get away with being broadcast on network TV!! ABC, NBC or Fox: ultimately, I think Twin Peaks would have self-destructed. It never really belonged on a regular network. It was a binge-watching streaming miniseries before such a thing existed.
