We hosted the only Olympics in history that I've heard of that turned a profit. I live in Calgary and we still talk about how unique it was compared to other Olympics around the world.
There are definitely some winners post-Olympics, but honestly I don't think they make sense anymore. Seems that Olympics has gone down the wrong path in so many ways with the demands from the IOC requiring bigger and bigger budgets, private organizations taking stricter and stricter control over content even social media that it's just not the same any more when compared to 20+ years ago.
I remember feeling an emotion for the older Olympics that's just not there as much anymore.
