have chosen to relocate out of a difficult market, to better facilities, or to realize the market value of the land that the current stadium is built upon (A famous example being the Relocation of Wimbledon F.C. to Milton Keynes). As in the U.S., team relocations have been controversial as supporters of the club will protest at its loss. Systems around the world Leagues around the world generally follow one or the other of these systems with some variation. Most sport leagues in Australia are similar to the North American model, using post-season playoffs and no relegation, but without geographical divisions, with the most notable examples being the Australian Football League (Aussie rules) and National Rugby League (rugby league). Nippon Professional Baseball in Japan uses the North American system due to American influence on the game. In cricket, the Indian Premier League, launched in 2008, also operates on this system. The Super League, which is the top level of rugby league in the United Kingdom and France (also with a Canadian team), was run on a franchise basis from 2009 to 2014, but returned to a promotion-relegation model with the 2015 season. Another example of a franchised league in European sport is ice hockey's Kontinental Hockey League, centered mainly in Russia with teams also located in Belarus, China, and Kazakhstan. Rugby union also has a European-based franchised league in the United Rugby Championship (historically the Celtic League, Pro12, and Pro14). It was founded with teams in the Celtic nations of Ireland, Scotland, and Wales, and later added teams outside those nations, first from Italy and then South Africa. The promotion-relegation system is widely used in football around the world, notably in Africa and Latin America as well as Europe. The most notable variation has developed in Latin America where many countries have two league seasons per year, which scheduling allows because many Latin American nations lack a national cup competition. Another notable variation is the Brazilian system of two parallel league systems each with its own separate promotion and relegation, one national and another on state-level, the same teams play both leagues each year. The European model is also used in Europe even when the sports were founded in America, showing that the league system adopted is not determined by the sport itself, but more on the tradition of sports organization in that region.
