International cricket
Most games are played as parts of "tours", when one nation travels to another for a number of weeks or months, and plays a number of matches of various sorts against the host nation. The ICC also organises competitions that are for several countries at once, including the Cricket World Cup & ICC T20 World Cup.
Cricket World Cup hosts
The International Cricket Council's executive committee votes for the hosts of the tournament after examining the bids made by the nations keen to hold a Cricket World Cup. All the World Cup events so far have been held in nations in which cricket is a popular sport. Most of the tournaments have been jointly hosted by nations from the same geographical region, such as South Asia  in 1987, 1996, and 2011, Australasia in 1992 and 2015, Southern Africa in 2003 and West Indies in 2007.
