The International Olympic Committee was an organization responsible for organizing the summer and winter versions of the Olympic Games in the modern era. Established in 1894, the IOC restarted the summer games in Athens in 1896 and the winter games in Chamonix, France, in 1924. 1980 was when the last summer games, in Moscow, USSR, and the last winter games, in Lake Placid, New York, U.S.A., were held. It was restarted in 2001 by the ANZC and Brazilian national sports federations, and is currently headquartered in Auckland, ANZC, the site where the summer games will resume in 2012. The winter games resumed in February, 2010 at various sites in the Alpine Confederation, with 19 countries competing in 11 sports.
Discussions for post-war resumption of the Olympic games and the re-establishment of the IOC go back as far as 1986, when FIFA, the sanctioning body for world soccer, announced plans to resume the World Cup tournament in 1990. For various reasons, most cited being the massive costs and logistics necessary for such a venture in a post-war world being too much for one country to shoulder, any move to resume the Olympics never got beyond the discussion stage. Also, South American, European and Oceanic countries could not agree on how to reform the IOC.
Finally in 2001, the ANZC and Brazilian sports federations leaders met in Santiago, Chile, and agreed to form a plan to resume the summer Olympic games within the next 10 years. The two federations took the lead on reforming the IOC, placing the headquarters in Auckland until 2011, and over the next several years two dozen nations joined the organization.
In 2006, the IOC announced the summer Olympics would resume in 2010 in Auckland, ANZC. In November 2009, the games were postponed to 2012. Throughout 2009, a move to postpone the summer games had gained popularity amongst national sports federations and certain IOC officials. Three reasons drove this move: first, a desire amongst IOC officials to have the Games back on the traditional schedule - 2010 was two years removed from that - second, a desire amongst sports federations of nations competing in the football World Cup to not hold an Olympics weeks after that event concluded, and third, several poorer nations wanted two additional years to get themselves up to sufficient standards to compete.
The IOC approved regional competitions for each continent in 2010, as a way for national federations to prepare for Auckland in both competition and organization. The Virginian Republic announced on November 21, 2009, that it had begun preparations for a North American regional Olympic-style competition in the summer of 2010. The ANZC's national sports federation was organizing an Oceanic/Asian Games for September 2010.
When the games officially resumed in 2012, following a smaller winter games held as a test in 2010 in the Alpine Confederation, the IOC referred to them as the Games of the XXX Summer Olympiad, despite the widespread destruction in the wake of Doomsday, and no games having been held since 1980. As Olympiads are recognized for 1916, 1940 and 1944 (when competition was canceled due to World Wars I and II), it only made sense to extend that protocol for 1984, 1988, 1992, 1996, 2000, 2004, and 2008 as well.
Also in 2009, the IOC voted to move the Games of the XXXI Olympiad to 2016. On November 24, 2009, the IOC awarded the 2016 games to Rio de Janeiro, Brazil. The vote for the 2014 Winter Games was held in February of 2010, with Trondheim, Nordic Union, being named the host city.
Santiago, Chile and Lausanne, Alpine Confederation - the headquarters for the pre-Doomsday IOC - have bid to become the new headquarters for the IOC when it moves from Auckland. The new headquarters was to be decided in February 2010, but politics and bickering postponed the vote indefinitely.
Politicking for the 2018 Winter Games has already begun, with Siberia and Canada pushing hard to be the host nation, and Japan putting in a formal bid in September of 2010, though withdrawing it following the Tōhoku Earthquake and Tsunami in March of 2011. The countries that are not selected for 2018 are expected to bid for 2022, along with Prussia/North Germany. Bids for 2018 are due by the end of February, 2013, and the winning bid will be chosen that October.
The host country for the 2020 Summer Games will be selected in September of 2014, but where it will be held is being widely debated. Prussia, Siberia, Mexico, Singapore, New Britain and Virginia have all shown great interest. Bids are due by the end of January, 2014.
