Worlds Fairs were once the kind of thing that could be seen as potentially bettering the future of your city simply by managing to win the bid to hold one, kind of like the Olympics. We still hear all about the Olympics each and every game, but while Worlds Fairs are still going on, they don't seem to get much attention at all. So what happened exactly? Why do we pay less attention to them, in a time when the world is more globalized than ever?

I am also curious if they took time to reach the popularity they had in the era they were giving us things like the Eiffel Tower and the Ferris Wheel in, or were they well received from early on?
