<P> To avoid any future boycotts or controversy, FIFA began a pattern of alternation between the Americas and Europe, which continued until the 2002 FIFA World Cup which took place in Asia . The system evolved so that the host country is now chosen in a vote by FIFA's Council (former Executive Committee). This is done under an exhaustive ballot system . The decision is currently made roughly seven years in advance of the tournament, though the hosts for the 2022 tournament were chosen at the same time as those for the 2018 tournament . </P> <P> Only Mexico, Italy, France, Germany (West Germany until shortly after the 1990 World Cup) and Brazil have hosted the event on two occasions . Mexico City's Estadio Azteca and Rio de Janeiro's Maracanã are the only venues ever to have hosted two FIFA World Cup finals . Only the 2002 FIFA World Cup had more than one host, being split between Japan and South Korea . </P> <Table> <Tr> <Th> Year </Th> <Th> Host </Th> <Th> Continent </Th> <Th> Winner </Th> </Tr> <Tr> <Td> 1930 </Td> <Td> Uruguay </Td> <Td> South America </Td> <Td> Uruguay </Td> </Tr> <Tr> <Td> 1934 </Td> <Td> Italy </Td> <Td> Europe </Td> <Td> Italy </Td> </Tr> <Tr> <Td> 1938 </Td> <Td> France </Td> <Td> Europe </Td> <Td> Italy </Td> </Tr> <Tr> <Td> 1942 </Td> <Td_colspan="3"> Cancelled due to World War II </Td> </Tr> <Tr> <Td> 1946 </Td> <Td_colspan="3"> Cancelled due to World War II </Td> </Tr> <Tr> <Td> 1950 </Td> <Td> Brazil </Td> <Td> South America </Td> <Td> Uruguay </Td> </Tr> <Tr> <Td> 1954 </Td> <Td> Switzerland </Td> <Td> Europe </Td> <Td> West Germany </Td> </Tr> <Tr> <Td> 1958 </Td> <Td> Sweden </Td> <Td> Europe </Td> <Td> Brazil </Td> </Tr> <Tr> <Td> 1962 </Td> <Td> Chile </Td> <Td> South America </Td> <Td> Brazil </Td> </Tr> <Tr> <Td> 1966 </Td> <Td> England </Td> <Td> Europe </Td> <Td> England </Td> </Tr> <Tr> <Td> 1970 </Td> <Td> Mexico </Td> <Td> North America </Td> <Td> Brazil </Td> </Tr> <Tr> <Td> </Td> <Td> West Germany </Td> <Td> Europe </Td> <Td> West Germany </Td> </Tr> <Tr> <Td> 1978 </Td> <Td> Argentina </Td> <Td> South America </Td> <Td> Argentina </Td> </Tr> <Tr> <Td> 1982 </Td> <Td> Spain </Td> <Td> Europe </Td> <Td> Italy </Td> </Tr> <Tr> <Td> 1986 </Td> <Td> Mexico </Td> <Td> North America </Td> <Td> Argentina </Td> </Tr> <Tr> <Td> 1990 </Td> <Td> Italy </Td> <Td> Europe </Td> <Td> West Germany </Td> </Tr> <Tr> <Td> 1994 </Td> <Td> United States </Td> <Td> North America </Td> <Td> Brazil </Td> </Tr> <Tr> <Td> 1998 </Td> <Td> France </Td> <Td> Europe </Td> <Td> France </Td> </Tr> <Tr> <Td> 2002 </Td> <Td> South Korea / Japan </Td> <Td> Asia </Td> <Td> Brazil </Td> </Tr> <Tr> <Td> 2006 </Td> <Td> Germany </Td> <Td> Europe </Td> <Td> Italy </Td> </Tr> <Tr> <Td> </Td> <Td> South Africa </Td> <Td> Africa </Td> <Td> Spain </Td> </Tr> <Tr> <Td> 2014 </Td> <Td> Brazil </Td> <Td> South America </Td> <Td> Germany </Td> </Tr> <Tr> <Td> 2018 </Td> <Td> Russia </Td> <Td> Europe </Td> <Td> </Td> </Tr> <Tr> <Td> 2022 </Td> <Td> Qatar </Td> <Td> Asia </Td> <Td> </Td> </Tr> <Tr> <Td> 2026 </Td> <Td> TBD </Td> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td> 2030 </Td> <Td> TBD </Td> <Td> </Td> <Td> </Td> </Tr> </Table> <Tr> <Th> Year </Th> <Th> Host </Th> <Th> Continent </Th> <Th> Winner </Th> </Tr>
