2016 Summer Olympics: Rio de Janeiro, Brazil
Rio de Janeiro became the first South American nation to host the Olympics when the IOC awarded the Games to the city for 2016. Yet the decision proved to be short-sighted, as the city and Brazil as a whole did not have infrastructure like venues and transportation already in place.

American gymnast Simone Biles emerged as the star of the Games, taking home four golds and a bronze.
