LIST OF CITIES THAT HOSTED THE OLYMPICS
This is a searchable database with all the cities that hosted the Olympic Games (winter olympics and summer olympics).
Host cities are selected by the International Olympic Committee (IOC). Currently, they are selected seven years in advance.
The selection process takes two years. In the first stage of the selection process, any city in the world may submit an application to become a host city.
After ten months, the Executive Board of the IOC decides which of these applicant cities will become candidate cities based on the recommendation of a working group that reviews the applications. In the second stage, the candidate cities are investigated thoroughly by an Evaluation Commission, which then submits a final short list of cities to be considered for selection. The host city is then chosen by vote of the IOC Session, a general meeting of IOC members (source: wikipedia.org).
