Youth Olympic Games
The evolution of the Olympic Movement during the 20th and 21st centuries has resulted in several changes to the Olympic Games. Some of these adjustments include the creation of the Winter Games for ice and winter sports, the Paralympic Games for athletes with a physical disability, and the Youth Olympic Games for teenage athletes. The IOC has had to adapt to the varying economic, political, and technological realities of the 20th century. As a result, the Olympics shifted away from pure amateurism, as envisioned by Coubertin, to allow participation of professional athletes. The growing importance of the mass media created the issue of corporate sponsorship and commercialization of the Games. World Wars led to the cancellation of the 1916, 1940, and 1944 Games. Large boycotts during the Cold War limited participation in the 1980 and 1984 Games.
The Olympic Movement consists of international sports federations (IFs), National Olympic Committees (NOCs), and organizing committees for each specific Olympic Games. As the decision-making body, the IOC is responsible for choosing the host city for each Olympic Games. The host city is responsible for organizing and funding a celebration of the Games consistent with the Olympic Charter. The Olympic program, consisting of the sports to be contested at the Games, is also determined by the IOC. The celebration of the Games encompasses many rituals and symbols, such as the Olympic flag and torch, as well as the opening and closing ceremonies. Over 13,000 athletes compete at the Summer and Winter Olympics in 33 different sports and nearly 400 events. The first, second, and third place finishers in each event receive Olympic medals: gold, silver, and bronze, respectively.
The Games have grown in scale to the point that nearly every nation is represented. Such growth has created numerous challenges, including boycotts, doping, bribery of officials, and terrorism. Every two years, the Olympics and its media exposure provide unknown athletes with the chance to attain national, and in particular cases, international fame. The Games also constitute a major opportunity for the host city and country to showcase itself to the world.
Ancient Olympicscity-states and kingdoms from Ancient Greece, which featured mainly athletic but also combat and chariot racing events. During the Olympic games all struggles against the participating city-states were postponed until the games were finished. The origin of these Olympics is shrouded in mystery and legend. One of the most popular myths identifies Heracles and his father Zeus as the progenitors of the Games. According to legend, it was Heracles who first called the Games "Olympic" and established the custom of holding them every four years. A legend persists that after Heracles completed his twelve labors, he built the Olympic stadium as an honor to Zeus. Following its completion, he walked in a straight line for 200 steps and called this distance a "stadion" (Greek: στάδιον, Latin: stadium, "stage"), which later became a unit of distance. Another myth associates the first Games with the ancient Greek concept of Olympic truce (ἐκεχειρία, ekecheiria). The most widely accepted date for the inception of the Ancient Olympics is 776 BC; this is based on inscriptions, found at Olympia, of the winners of a footrace held every four years starting in 776 BC. The Ancient Games featured running events, a pentathlon (consisting of a jumping event, discus and javelin throws, a foot race and wrestling), boxing, wrestling, pankration, and equestrian events. Tradition has it that Coroebus, a cook from the city of Elis, was the first Olympic champion.
The Olympics were of fundamental religious importance, featuring sporting events alongside ritual sacrifices honoring both Zeus (whose famous statue by Phidias stood in his temple at Olympia) and Pelops, divine hero and mythical king of Olympia. Pelops was famous for his chariot race with King Oenomaus of Pisatis. The winners of the events were admired and immortalized in poems and statues. The Games were held every four years, and this period, known as an Olympiad, was used by Greeks as one of their units of time measurement. The Games were part of a cycle known as the Panhellenic Games, which included the Pythian Games, the Nemean Games, and the Isthmian Games.
The Olympic Games reached their zenith in the 6th and 5th centuries BC, but then gradually declined in importance as the Romans gained power and influence in Greece. There is no consensus on when the Games officially ended, the most common-held date is 393 AD, when the emperor Theodosius I declared that all pagan cults and practices be eliminated. Another date cited is 426 AD, when his successor Theodosius II ordered the destruction of all Greek temples. After the demise of the Olympics, they were not held again until the late 19th century.
 Modern Games
 ForerunnersRevolutionary France. The competition included several disciplines from the ancient Greek Olympics. The 1796 Games also marked the introduction of the metric system into sport.
In 1850 an Olympian Class was started by Dr William Penny Brookes at Much Wenlock, in Shropshire, England. In 1859, Dr Brookes changed the name to Wenlock Olympian Games. This annual sports festival continues to this day. The Wenlock Olympian Society was founded by Dr. Brookes on 15 November 1860.:28
Between 1862 and 1867, Liverpool held an annual Grand Olympic Festival. Devised by John Hulley and Charles Melly, these games were the first to be wholly amateur in nature and international in outlook, although only 'gentlemen amateurs' could compete. The programme of the first modern Olympiad in Athens in 1896 was almost identical to that of the Liverpool Olympics. In 1865 Hulley, Dr. Brookes and E.G. Ravenstein founded the National Olympian Association in Liverpool, a forerunner of the British Olympic Association. Its articles of foundation provided the framework for the International Olympic Charter. In 1866, a national Olympic Games in Great Britain was organized at London's Crystal Palace.
 RevivalGreek War of Independence from the Ottoman Empire in 1821. It was first proposed by poet and newspaper editor Panagiotis Soutsos in his poem "Dialogue of the Dead", published in 1833.:1 Evangelis Zappas, a wealthy Greek-Romanian philanthropist, first wrote to King Otto of Greece, in 1856, offering to fund a permanent revival of the Olympic Games.:14 Zappas sponsored the first Olympic Games in 1859, which was held in an Athens city square. Athletes participated from Greece and the Ottoman Empire. Zappas funded the restoration of the ancient Panathenaic stadium so that it could host all future Olympic Games.:14
The Panathinaiko Stadium hosted Olympics in 1870 and 1875.:2, 13–23, 81 Thirty thousand spectators attended that Games in 1870 though no official attendance records are available for the 1875 Games.:44 In 1890, after attending the Olympian Games of the Wenlock Olympian Society, Baron Pierre de Coubertin was inspired to found the International Olympic Committee (IOC). Coubertin built on the ideas and work of Brookes and Zappas with the aim of establishing internationally rotating Olympic Games that would occur every four years. He presented these ideas during the first Olympic Congress of the newly created International Olympic Committee. This meeting was held from 16 to 23 June 1894, at the Sorbonne University in Paris. On the last day of the Congress, it was decided that the first Olympic Games, to come under the auspices of the IOC, would take place in Athens in 1896. The IOC elected the Greek writer Demetrius Vikelas as its first president.:100–105
 1896 GamesPanathenaic stadium in Athens in 1896. These Games brought together 14 nations and 241 athletes who competed in 43 events. Zappas and his cousin Konstantinos Zappas had left the Greek government a trust to fund future Olympic Games. This trust was used to help finance the 1896 Games.:117 George Averoff contributed generously for the refurbishment of the stadium in preparation for the Games.:128 The Greek government also provided funding, which was expected to be recouped through the sale of tickets to the Games and from the sale of the first Olympic commemorative stamp set.:128
The Greek officials and public were enthusiastic about the experience of hosting these Games. This feeling was shared by many of the athletes, who even demanded that Athens be the host of the Olympic Games on a permanent basis. The IOC did not approve this request. The committee planned that the modern Olympics would rotate internationally. They consequently decided to hold the second Games in Paris.
 Changes and adaptationsAfter the success of the 1896 Games, the Olympics entered a period of stagnation that threatened their survival. The Olympic Games held at the Paris Exposition in 1900 and the World's Fair at St. Louis in 1904 were side-shows. The Games at Paris did not have a stadium; however, this was the first time women took part in the games. The St. Louis Games hosted 650 athletes, but 580 were from the United States. The homogeneous nature of these celebrations was a low point for the Olympic Movement. The Games rebounded when the 1906 Intercalated Games (so-called because they were the second Games held within the third Olympiad) were held in Athens. These Games are not officially recognized by the IOC and no Intercalated Games have been held since. These Games, which were hosted at the Panathenaic stadium in Athens, attracted a broad international field of participants, and generated great public interest. This marked the beginning of a rise in both the popularity and the size of the Olympics.
 Winter Games1921 Olympic Congress, in Lausanne, it was decided to hold a winter version of the Olympic Games. A winter sports week (it was actually 11 days) was held in 1924 in Chamonix, France; this event became the first Winter Olympic Games. The IOC mandated that the Winter Games be celebrated every four years on the same year as their summer counterpart. This tradition was upheld until the 1992 Games in Albertville, France; after that, beginning with the 1994 Games, the Winter Olympics were held on the third year of each Olympiad.
 ParalympicsIn 1948, Sir Ludwig Guttmann, determined to promote the rehabilitation of soldiers after World War II, organized a multi-sport event between several hospitals to coincide with the 1948 London Olympics. Guttmann's event, known then as the Stoke Mandeville Games, became an annual sports festival. Over the next twelve years, Guttmann and others continued their efforts to use sports as an avenue to healing. For the 1960 Olympic Games, in Rome, Guttmann brought 400 athletes to compete in the "Parallel Olympics", which became known as the first Paralympics. Since then, the Paralympics have been held in every Olympic year. As of the 1988 Summer Olympics in Seoul, South Korea, the host city for the Olympics has also played host to the Paralympics. In 2001 the International Olympic Committee (IOC) and the International Paralympic Committee (IPC) signed an agreement which guaranteed that host cities would be contracted to manage both the Olympic and Paralympic Games. The agreement came into effect at the Summer Games in Beijing 2008, and the Winter Games in Vancouver 2010. Chairman of the London organising committee, Lord Coe, said about the 2012 Summer Paralympics and Olympics in London, England that,
|“||We want to change public attitudes towards disability, celebrate the excellence of Paralympic sport and to enshrine from the very outset that the two Games are an integrated whole.||”|
 Youth GamesIn 2010, the Olympic Games were complemented by the Youth Games, which gives athletes between the ages of 14 and 18 the chance to compete. The Youth Olympic Games were conceived by IOC president Jacques Rogge in 2001 and approved during the 119th Congress of the IOC. The first Summer Youth Games were held in Singapore from 14–26 August 2010, while the inaugural Winter Games will be hosted in Innsbruck, Austria, two years later. These Games will be shorter than the senior Games; the summer version will last twelve days, while the winter version will last nine days. The IOC allows 3,500 athletes and 875 officials to participate at the Summer Youth Games, and 970 athletes and 580 officials at the Winter Youth Games. The sports to be contested will coincide with those scheduled for the senior Games, however there will be variations on the sports including mixed NOC and mixed gender teams as well as a reduced number of disciplines and events.
 Recent gamesFrom 241 participants representing 14 nations in 1896, the Games have grown to about 10,500 competitors from 204 countries at the 2008 Summer Olympics. The scope and scale of the Winter Olympics is smaller. For example, Turin hosted 2,508 athletes from 80 countries competing in 84 events, during the 2006 Winter Olympics. During the Games most athletes and officials are housed in the Olympic village. This village is intended to be a self-contained home for all the Olympic participants. It is furnished with cafeterias, health clinics, and locations for religious expression.
The IOC allowed the formation of National Olympic Committees representing countries that did not meet the strict requirements for political sovereignty that other international organizations demand. As a result, colonies and dependencies are permitted to compete at Olympic Games. Examples of this include territories such as Puerto Rico, Bermuda and Hong Kong, all of which compete as separate nations despite being legally a part of another country. The current version of the Charter does only allow new National Olympic Committees representing "independent State recognised by the international community". It therefore did not allow the formation of National Olympic Committees for Sint Maarten and Curaçao when they gained the same constitutional status as Aruba in 2010, although it recognized the Aruban Olympic Committee in 1986.
 International Olympic CommitteeOlympic Charter. As the umbrella organization of the Olympic Movement, the International Olympic Committee (IOC) is responsible for selecting the host city, overseeing the planning of the Olympic Games, updating and approving the sports program, and negotiating sponsorship and broadcasting rights. The Olympic Movement is made of three major elements:
- International Federations (IFs) are the governing bodies that supervise a sport at an international level. For example, the International Federation of Association Football (FIFA) is the IF for football (soccer), and the Fédération Internationale de Volleyball (FIVB) is the international governing body for volleyball. There are currently 35 IFs in the Olympic Movement, representing each of the Olympic sports.
- National Olympic Committees (NOCs) represent and regulate the Olympic Movement within each country. For example, the United States Olympic Committee (USOC) is the NOC of the United States. There are currently 205 NOCs recognized by the IOC.
- Organizing Committees for the Olympic Games (OCOGs) constitute the temporary committees responsible for the organization of a specific celebration of the Olympics. OCOGs are dissolved after each Games, once the final report is delivered to the IOC.
 CriticismThe IOC has often been criticized for being an intractable organization, with several members on the committee for life. The leadership of IOC presidents Avery Brundage and Juan Antonio Samaranch was especially controversial. Brundage was president for over 20 years, and during his tenure he protected the Olympics from political involvement. He was accused of both racism, for his handling of the apartheid issue with the South African delegation, and anti-Semitism. Under the Samaranch presidency, the office was accused of both nepotism and corruption. Samaranch's ties with the Franco regime in Spain were also a source of criticism.
In 1998, it was uncovered that several IOC members had taken bribes from members of the Salt Lake City bid committee for the hosting of the 2002 Winter Olympics, to ensure their votes were cast in favor of the American bid. The IOC pursued an investigation which led to the resignation of four members and expulsion of six others. The scandal set off further reforms that would change the way host cities are selected, to avoid similar cases in the future.
A BBC documentary entitled Panorama: Buying the Games, aired in August 2004, investigated the taking of bribes in the bidding process for the 2012 Summer Olympics. The documentary claimed it was possible to bribe IOC members into voting for a particular candidate city. After being narrowly defeated in their bid for the 2012 Summer Games, Parisian Mayor Bertrand Delanoë specifically accused the British Prime Minister Tony Blair and the London Bid Committee (headed by former Olympic champion Sebastian Coe) of breaking the bid rules. He cited French President Jacques Chirac as a witness; Chirac gave guarded interviews regarding his involvement. The allegation was never fully explored. The Turin bid for the 2006 Winter Olympics was also shrouded in controversy. A prominent IOC member, Marc Hodler, strongly connected with the rival bid of Sion, Switzerland, alleged bribery of IOC officials by members of the Turin Organizing Committee. These accusations led to a wide-ranging investigation. The allegations also served to sour many IOC members against Sion's bid and potentially helped Turin to capture the host city nomination.
 CommercializationThe IOC originally resisted funding by corporate sponsors. It was not until the retirement of IOC president Avery Brundage, in 1972, that the IOC began to explore the potential of the television medium and the lucrative advertising markets available to them. Under the leadership of Juan Antonio Samaranch the Games began to shift toward international sponsors who sought to link their products to the Olympic brand.
 BudgetDuring the first half of the 20th century the IOC ran on a small budget. As president of the IOC from 1952 to 1972, Avery Brundage rejected all attempts to link the Olympics with commercial interest. Brundage believed the lobby of corporate interests would unduly impact the IOC's decision-making. Brundage's resistance to this revenue stream meant the IOC left organizing committees to negotiate their own sponsorship contracts and use the Olympic symbols. When Brundage retired the IOC had US$2 million in assets; eight years later the IOC coffers had swelled to US$45 million. This was primarily due to a shift in ideology toward expansion of the Games through corporate sponsorship and the sale of television rights. When Juan Antonio Samaranch was elected IOC president in 1980 his desire was to make the IOC financially independent.
The 1984 Summer Olympics became a watershed moment in Olympic history. The Los Angeles-based organizing committee, led by Peter Ueberroth, was able to generate a surplus of US$225 million, which was an unprecedented amount at that time. The organizing committee had been able to create such a surplus in part by selling exclusive sponsorship rights to select companies. The IOC sought to gain control of these sponsorship rights. Samaranch helped to establish The Olympic Program (TOP) in 1985, in order to create an Olympic brand. Membership in TOP was, and is, very exclusive and expensive. Fees cost US$50 million for a four year membership. Members of TOP received exclusive global advertising rights for their product category, and use of the Olympic symbol, the interlocking rings, in their publications and advertisements.
 Effect of television1936 Summer Olympics in Berlin were the first Games to be broadcast on television, though only to local audiences. The 1956 Winter Olympics were the first internationally televised Olympic Games, and the following Winter Games had their broadcasting rights sold for the first time to specialized television broadcasting networks—CBS paid US$394,000 for the American rights, and the European Broadcasting Union (EBU) allocated US$660,000. In the following decades the Olympics became one of the ideological fronts of the Cold War. Superpowers jockeyed for political supremacy, and the IOC wanted to take advantage of this heightened interest via the broadcast medium. The sale of broadcast rights enabled the IOC to increase the exposure of the Olympic Games, thereby generating more interest, which in turn created more appeal to advertisers time on television. This cycle allowed the IOC to charge ever-increasing fees for those rights. For example, CBS paid US$375 million for the rights of the 1998 Nagano Games, while NBC spent US$3.5 billion for the broadcast rights of all the Olympic Games from 2000 to 2012.
Viewership increased exponentially from the 1960s until the end of the century. This was due to the use of satellites to broadcast live television worldwide in 1964, and the introduction of color television in 1968. Global audience estimates for the 1968 Mexico City Games was 600 million, whereas at the Los Angeles Games of 1984, the audience numbers had increased to 900 million; that number swelled to 3.5 billion by the 1992 Summer Olympics in Barcelona. However, at the 2000 Summer Games in Sydney, NBC drew the lowest ratings for any Summer or Winter Olympics since 1968. This was attributed to two factors: one was the increased competition from cable channels, the second was the internet, which was able to display results and video in real time. Television companies were still relying on tape-delayed content, which was becoming outdated in the information era. A drop in ratings meant that television studios had to give away free advertising time. With such high costs charged to broadcast the Games, the added pressure of the internet, and increased competition from cable, the television lobby demanded concessions from the IOC to boost ratings. The IOC responded by making a number of changes to the Olympic program. At the Summer Games, the gymnastics competition was expanded from seven to nine nights, and a Champions Gala was added to draw greater interest. The IOC also expanded the swimming and diving programs, both popular sports with a broad base of television viewers. Finally, the American television lobby was able to dictate when certain events were held so that they could be broadcast live during prime time in the United States. The result of these efforts was mixed: the ratings for the 2006 Winter Games, held in Torino, Italy, were significantly lower than those for the 2002 Games, while there was a sharp increase in viewership for the 2008 Summer Olympics, staged in Beijing.
 ControversyThe sale of the Olympic brand has been controversial. The argument is that the Games have become indistinguishable from any other commercialized sporting spectacle. Specific criticism was levelled at the IOC for market saturation during the 1996 Atlanta and 2000 Sydney Games. The cities were awash in corporations and merchants attempting to sell Olympic-related wares. The IOC indicated that they would address this to prevent spectacles of over-marketing at future Games. Another criticism is that the Games are funded by host cities and national governments; the IOC incurs none of the cost, yet controls all the rights and profits from the Olympic symbols. The IOC also takes a percentage of all sponsorship and broadcast income. Host cities continue to compete ardently for the right to host the Games, even though there is no certainty that they will earn back their investments.
 CostThe cost of the Olympic Games (Summer and Winter) have been studied by Oxford scholars Bent Flyvbjerg and Allison Stewart. They found that over the past 50 years the most costly Games have been London 2012 (USD14.8 billion), Barcelona 1992 (USD11.4 billion), and Montreal 1976 (USD6 billion). Beijing 2008 may have been more costly or not; the Chinese authorities have not released the data that would allow verification of either position. Cost here includes only sports-related costs and thus does not include other public costs, such as road, rail, or airport infrastructure, or private costs, such as hotel upgrades or other business investments incurred in preparation of the Games, which are typically substantial but which vary drastically from city to city and are difficult to compare consistently. 
Flyvbjerg and Stewart further found that cost overrun is a persistent problem for the Olympic Games:
- The Games overrun with 100 per cent consistency. No other type of megaproject is this predictable regarding cost overrun. Other megaprojects – in construction, infrastructure, dams, ICT – are typically on budget from time to time, but not the Olympics.
- With an average cost overrun in real terms of 179 per cent – and 324 per cent in nominal terms – overruns in the Games have historically been significantly larger than for other types of megaprojects.
- The largest cost overruns have been incurred by Montreal 1976 (796%), Barcelona 1992 (417%), and Lake Placid 1980 (321%), all in real terms.
- The data show that for a city and nation to decide to host the Olympic Games is to take on one of the most financially risky type of megaproject that exists, something that many cities and nations have learned to their peril. For example, cost overrun and debt from Athens 2004 substantially worsened Greece's financial and economic crises 2008–12. Montreal took 30 years to pay off the debt from the 1976 Games.
 SymbolsOlympic rings, consists of five intertwined rings and represents the unity of the five inhabited continents (America, Africa, Asia, Australasia, Europe). The colored version of the rings—blue, yellow, black, green, and red—over a white field forms the Olympic flag. These colors were chosen because every nation had at least one of them on its national flag. The flag was adopted in 1914 but flown for the first time only at the 1920 Summer Olympics in Antwerp, Belgium. It has since been hoisted during each celebration of the Games.
The Olympic motto is Citius, Altius, Fortius, a Latin expression meaning "Faster, Higher, Stronger". Coubertin's ideals are further expressed in the Olympic creed:
Months before each Games, the Olympic flame is lit in Olympia in a ceremony that reflects ancient Greek rituals. A female performer, acting as a priestess, ignites a torch by placing it inside a parabolic mirror which focuses the sun's rays; she then lights the torch of the first relay bearer, thus initiating the Olympic torch relay that will carry the flame to the host city's Olympic stadium, where it plays an important role in the opening ceremony. Though the flame has been an Olympic symbol since 1928, the torch relay was introduced at the 1936 Summer Games, as part of the German government's attempt to promote its National Socialist ideology.The most important thing in the Olympic Games is not to win but to take part, just as the most important thing in life is not the triumph but the struggle. The essential thing is not to have conquered but to have fought well.
The Olympic mascot, an animal or human figure representing the cultural heritage of the host country, was introduced in 1968. It has played an important part on the Games identity promotion since the 1980 Summer Olympics, when the Russian bear cub Misha reached international stardom. The mascots of the most recent Summer Olympics, in Beijing, were the Fuwa, five creatures that represent the five fengshui elements important in Chinese culture.
 Opening Most of these rituals were established at the 1920 Summer Olympics in Antwerp. The ceremony typically starts with the hoisting of the host country's flag and a performance of its national anthem. The host nation then presents artistic displays of music, singing, dance, and theater representative of its culture. The artistic presentations have grown in scale and complexity as successive hosts attempt to provide a ceremony that outlasts its predecessor's in terms of memorability. The opening ceremony of the Beijing Games reportedly cost $100 million, with much of the cost incurred in the artistic segment.
After the artistic portion of the ceremony, the athletes parade into the stadium grouped by nation. Greece is traditionally the first nation to enter in order to honor the origins of the Olympics. Nations then enter the stadium alphabetically according to the host country's chosen language, with the host country's athletes being the last to enter. During the 2004 Summer Olympics, which was hosted in Athens, Greece, the Greek flag entered the stadium first, while the Greek delegation entered last. Speeches are given, formally opening the Games. Finally, the Olympic torch is brought into the stadium and passed on until it reaches the final torch carrier—often a well-known and successful Olympic athlete from the host nation—who lights the Olympic flame in the stadium's cauldron.
 Closing The president of the organizing committee and the IOC president make their closing speeches, the Games are officially closed, and the Olympic flame is extinguished. In what is known as the Antwerp Ceremony, the mayor of the city that organized the Games transfers a special Olympic flag to the president of the IOC, who then passes it on to the mayor of the city hosting the next Olympic Games. After these compulsory elements, the next host nation briefly introduces itself with artistic displays of dance and theater representative of its culture.
 Medal presentation After the medals are given out by an IOC member, the national flags of the three medalists are raised while the national anthem of the gold medalist's country plays. Volunteering citizens of the host country also act as hosts during the medal ceremonies, as they aid the officials who present the medals and act as flag-bearers. For every Olympic event, the respective medal ceremony is held, at most, one day after the event's final. For the men's marathon, the competition is usually held early in the morning on the last day of Olympic competition and its medal ceremony is then held in the evening during the closing ceremony.
 SportsThe Olympic Games program consists of 35 sports, 30 disciplines and nearly 400 events. For example, wrestling is a Summer Olympic sport, comprising two disciplines: Greco-Roman and Freestyle. It is further broken down into fourteen events for men and four events for women, each representing a different weight class. The Summer Olympics program includes 26 sports, while the Winter Olympics program features 15 sports. Athletics, swimming, fencing, and artistic gymnastics are the only summer sports that have never been absent from the Olympic program. Cross-country skiing, figure skating, ice hockey, Nordic combined, ski jumping, and speed skating have been featured at every Winter Olympics program since its inception in 1924. Current Olympic sports, like badminton, basketball, and volleyball, first appeared on the program as demonstration sports, and were later promoted to full Olympic sports. Some sports that were featured in earlier Games were later dropped from the program.
Olympic sports are governed by international sports federations (IFs) recognized by the IOC as the global supervisors of those sports. There are 35 federations represented at the IOC. There are sports recognized by the IOC that are not included on the Olympic program. These sports are not considered Olympic sports, but they can be promoted to this status during a program revision that occurs in the first IOC session following a celebration of the Olympic Games. During such revisions, sports can be excluded or included in the program on the basis of a two-thirds majority vote of the members of the IOC. There are recognized sports that have never been on an Olympic program in any capacity, including chess and surfing.
In October and November 2004, the IOC established an Olympic Programme Commission, which was tasked with reviewing the sports on the Olympic program and all non-Olympic recognized sports. The goal was to apply a systematic approach to establishing the Olympic program for each celebration of the Games. The commission formulated seven criteria to judge whether a sport should be included on the Olympic program. These criteria are history and tradition of the sport, universality, popularity of the sport, image, athletes' health, development of the International Federation that governs the sport, and costs of holding the sport. From this study five recognized sports emerged as candidates for inclusion at the 2012 Summer Olympics: golf, karate, rugby union, roller sports and squash. These sports were reviewed by the IOC Executive Board and then referred to the General Session in Singapore in July 2005. Of the five sports recommended for inclusion only two were selected as finalists: karate and squash. Neither sport attained the required two-thirds vote and consequently they were not promoted to the Olympic program. In October 2009 the IOC voted to instate golf and rugby union as Olympic sports for the 2016 and 2020 Summer Olympic Games.
The 114th IOC Session, in 2002, limited the Summer Games program to a maximum of 28 sports, 301 events, and 10,500 athletes. Three years later, at the 117th IOC Session, the first major program revision was performed, which resulted in the exclusion of baseball and softball from the official program of the 2012 London Games. Since there was no agreement in the promotion of two other sports, the 2012 program will feature just 26 sports. The 2016 and 2020 Games will return to the maximum of 28 sports given the addition of rugby and golf.
 Amateurism and professionalismethos of the aristocracy as exemplified in the English Independent school greatly influenced Pierre de Coubertin. The independent schools subscribed to the belief that sport formed an important part of education, an attitude summed up in the saying mens sana in corpore sano, a sound mind in a sound body. In this ethos, a gentleman was one who became an all-rounder, not the best at one specific thing. There was also a prevailing concept of fairness, in which practicing or training was considered tantamount to cheating. Those who practiced a sport professionally were considered to have an unfair advantage over those who practiced it merely as a hobby.
The exclusion of professionals caused several controversies throughout the history of the modern Olympics. The 1912 Olympic pentathlon and decathlon champion Jim Thorpe was stripped of his medals when it was discovered that he had played semi-professional baseball before the Olympics. His medals were posthumously restored by the IOC in 1983 on compassionate grounds. Swiss and Austrian skiers boycotted the 1936 Winter Olympics in support of their skiing teachers, who were not allowed to compete because they earned money with their sport and were thus considered professionals.
As class structure evolved through the 20th century, the definition of the amateur athlete as an aristocratic gentleman became outdated. The advent of the state-sponsored "full-time amateur athlete" of the Eastern Bloc countries further eroded the ideology of the pure amateur, as it put the self-financed amateurs of the Western countries at a disadvantage. Nevertheless, the IOC held to the traditional rules regarding amateurism. Beginning in the 1970s, amateurism requirements were gradually phased out of the Olympic Charter. After the 1988 Games, the IOC decided to make all professional athletes eligible for the Olympics, subject to the approval of the IFs. As of 2004, the only sports in which no professionals compete are boxing and wrestling, although even this requires a definition of amateurism based on fight rules rather than on payment, as some boxers and wrestlers receive cash prizes from their National Olympic Committees. In men's football (soccer), only three professional players over the age of 23 are eligible to participate per team in the Olympic tournament.
 BoycottsOlympic Council of Ireland boycotted the 1936 Berlin Games, because the IOC insisted its team needed to be restricted to the Irish Free State rather than representing the entire island of Ireland. There were three boycotts of the 1956 Melbourne Olympics: Netherlands, Spain, and Switzerland refused to attend because of the repression of the Hungarian uprising by the Soviet Union, but did send an equestrian delegation to Stockholm; Cambodia, Egypt, Iraq and Lebanon boycotted the Games because of the Suez Crisis; and China (the "People's Republic of China") boycotted the Games because Taiwan (the "Republic of China") was allowed to compete in the games. In 1972 and 1976 a large number of African countries threatened the IOC with a boycott to force them to ban South Africa and Rhodesia, because of their segregationist regimes. New Zealand was also one of the African boycott targets, because its national rugby union team had toured apartheid-ruled South Africa. The IOC conceded in the first two cases, but refused to ban New Zealand on the grounds that rugby was not an Olympic sport. Fulfilling their threat, twenty African countries were joined by Guyana and Iraq in a Tanzania-led withdrawal from the Montreal Games, after a few of their athletes had already competed. Taiwan also decided to boycott these Games because the People's Republic of China (PRC) exerted pressure on the Montreal organizing committee to keep the delegation from the Republic of China (ROC) from competing under that name. The ROC refused a proposed compromise that would have still allowed them to use the ROC flag and anthem as long as the name was changed. Taiwan did not participate again until 1984, when it returned under the name of Chinese Taipei and with a special flag and anthem.
In 1980 and 1984, the Cold War opponents boycotted each other's Games. Sixty-five nations refused to compete at the Moscow Olympics in 1980 because of the Soviet invasion of Afghanistan. This boycott reduced the number of nations participating to 81, the lowest number since 1956. The Soviet Union and 14 of its Eastern Bloc partners (except Romania) countered by boycotting the Los Angeles Olympics of 1984, contending that they could not guarantee the safety of their athletes. Soviet officials defended their decision to withdraw from the Games by saying that "chauvinistic sentiments and an anti-Soviet hysteria are being whipped up in the United States". The boycotting nations of the Eastern Bloc staged their own alternate event, the Friendship Games, in July and August.
There had been growing calls for boycotts of Chinese goods and the 2008 Olympics in Beijing in protest of China's human rights record, and in response to Tibetan disturbances and ongoing conflict in Darfur. Ultimately, no nation supported a boycott. In August 2008, the government of Georgia called for a boycott of the 2014 Winter Olympics, set to be held in Sochi, Russia, in response to Russia's participation in the 2008 South Ossetia war.
 PoliticsNationalist Socialist Party as benevolent and peace-loving when they hosted the 1936 Games, though they used the Games to display Aryan superiority. Germany was the most successful nation at the Games, which did much to support their allegations of Aryan supremacy, but notable victories by African American Jesse Owens, who won four gold medals, and Hungarian Jew Ibolya Csák, blunted the message. The Soviet Union did not participate until the 1952 Summer Olympics in Helsinki. Instead, starting in 1928, the Soviets organized an international sports event called Spartakiads. During the interwar period of the 1920s and 1930s, communist and socialist organizations in several countries, including the United States, attempted to counter what they called the "bourgeois" Olympics with the Workers Olympics. It was not until the 1956 Summer Games that the Soviets emerged as a sporting superpower and, in doing so, took full advantage of the publicity that came with winning at the Olympics. Individual athletes have also used the Olympic stage to promote their own political agenda. At the 1968 Summer Olympics in Mexico City, two American track and field athletes, Tommie Smith and John Carlos, who finished first and third in the 200 meters, performed the Black Power salute on the victory stand. The second place finisher, Peter Norman of Australia, wore an Olympic Project for Human Rights badge in support of Smith and Carlos. In response to the protest, IOC President Avery Brundage told the United States Olympic Committee (USOC) to either send the two athletes home or withdraw the track and field team. The USOC opted for the former.
Currently, the government of Iran has taken steps to avoid any competition between its athletes and those from Israel. An Iranian judoka, Arash Miresmaeli, did not compete in a match against an Israeli during the 2004 Summer Olympics. Although he was officially disqualified for being overweight, Miresmaeli was awarded US$125,000 in prize money by the Iranian government, an amount paid to all Iranian gold medal winners. He was officially cleared of intentionally avoiding the bout, but his receipt of the prize money raised suspicion.
 Use of performance enhancing drugsmarathon at the 1904 Games, Thomas Hicks, was given strychnine and brandy by his coach. The only Olympic death linked to doping occurred at the Rome Games of 1960. During the cycling road race, Danish cyclist Knud Enemark Jensen fell from his bicycle and later died. A coroner's inquiry found that he was under the influence of amphetamines. By the mid-1960s, sports federations were starting to ban the use of performance enhancing drugs; in 1967 the IOC followed suit.
The first Olympic athlete to test positive for the use of performance enhancing drugs was Hans-Gunnar Liljenwall, a Swedish pentathlete at the 1968 Summer Olympics, who lost his bronze medal for alcohol use. The most publicized doping-related disqualification was that of Canadian sprinter Ben Johnson, who won the 100 meter dash at the 1988 Seoul Olympics but tested positive for stanozolol. His gold medal was subsequently stripped and awarded to runner-up Carl Lewis, who himself had tested positive for banned substances prior to the Olympics.
In the late 1990s, the IOC took the initiative in a more organized battle against doping, by forming the World Anti-Doping Agency (WADA) in 1999. There was a sharp increase in positive drug tests at the 2000 Summer Olympics and 2002 Winter Olympics. Several medalists in weightlifting and cross-country skiing were disqualified because of doping offenses. During the 2006 Winter Olympics, only one athlete failed a drug test and had a medal revoked. The IOC-established drug testing regimen (now known as the Olympic Standard) has set the worldwide benchmark that other sporting federations around the world attempt to emulate. During the Beijing games, 3,667 athletes were tested by the IOC under the auspices of the World Anti-Doping Agency. Both urine and blood tests were used to detect banned substances. Several athletes were barred from competition by their National Olympic Committees prior to the Games; only three athletes failed drug tests while in competition in Beijing.
 Gender discrimination1900 Summer Olympics in Paris, but at the 1992 Summer Olympics thirty-five countries were still fielding all-male delegations. This number dropped rapidly over the following years. In 1996, Lita Fariman was the first woman to compete for Iran at the Olympics, in shooting. In 2000, Bahrain sent two women competitors for the first time: Fatema Hameed Gerashi and Mariam Mohamed Hadi Al Hilli. In 2004, Robina Muqim Yaar and Friba Razayee became the first women to compete for Afghanistan at the Olympics. In 2008, the United Arab Emirates sent female athletes (Maitha Al Maktoum competed in taekwondo, and Latifa Al Maktoum in equestrian) to the Olympic Games for the first time. Both athletes were from Dubai's ruling family.
By 2010 only three countries had never sent female athletes to the Games: Brunei, Saudi Arabia and Qatar. Brunei had taken part in only three celebrations of the Games, sending a single athlete on each occasion, but Saudi Arabia and Qatar had been competing regularly with all-male teams. In 2010, the International Olympic Committee announced it would "press" these countries to enable and facilitate the participation of women for the 2012 Summer Games; Anita DeFrantz, chair of the IOC's Women and Sports Commission, suggested that countries be barred if they prevented women from competing. Shortly thereafter, the Qatar Olympic Committee announced that it "hoped to send up to four female athletes in shooting and fencing" to the 2012 Summer Games in London. In Saudi Arabia, by contrast, national law explicitly prohibited women from competing at the Olympics – the only country where this was the case.
In 2008, Ali Al-Ahmed, director of the Institute for Gulf Affairs, likewise called for Saudi Arabia to be barred from the Games, describing its ban on women athletes as a violation of the International Olympic Committee charter. He noted: "For the last 15 years, many international nongovernmental organizations worldwide have been trying to lobby the IOC for better enforcement of its own laws banning gender discrimination. [...] While their efforts did result in increasing numbers of women Olympians, the IOC has been reluctant to take a strong position and threaten the discriminating countries with suspension or expulsion." In July 2010, The Independent reported: "Pressure is growing on the International Olympic Committee to kick out Saudi Arabia, who are likely to be the only major nation not to include women in their Olympic team for 2012. [...] Should Saudi Arabia [...] send a male-only team to London, we understand they will face protests from equal rights and women's groups which threaten to disrupt the Games".
In June of 2012, The Saudi Arabian Embassy in London announced it would let its female athletes compete in the Olympics in 2012 for the first time. Qatar and Brunei also reversed course in 2012 and said they would send athletes to the games that begin 27 July in London, England. Ultimately, Saudi Arabia included two female athletes in its delegation; Qatar, four; and Brunei, one (Maziah Mahusin, in the 400m hurdles). Qatar made one of its first female Olympians, Bahiya al-Hamad (shooting), its flagbearer at the 2012 Games.
The only sport on the Olympic programme that features men and women competing together is the equestrian disciplines. There is no "Women's Eventing", or 'Men's Dressage'. As of 2008 there were still more medal events for men than women. With the addition of women's boxing to the programme in the 2012 Summer Olympics, however, female athletes will be able to compete in all the same sports as men.
There are currently two Olympic events which male athletes may not compete at: synchronized swimming and rhythmic gymnastics.
Saudi Arabia agreed on July 12, 2012 to send two women to compete in the 2012 Olympic games in London, England. The two female athletes are Wodjan Ali Seraj Abdulrahim Shahrkhani in judo and 800-meter runner Sarah Attar. Prior to June 2012, Saudi Arabia had banned female athletes from competing at the Olympics. Every country competing at the London Games will include female athletes for the first time in Olympic history.
 ViolenceThree Olympiads had to pass without a celebration of the Games because of war: the 1916 Games were cancelled because of World War I, and the summer and winter games of 1940 and 1944 were cancelled because of World War II. The South Ossetia War between Georgia and Russia erupted on the opening day of the 2008 Summer Olympics in Beijing. Both President Bush and Prime Minister Putin were attending the Olympics at that time and spoke together about the conflict at a luncheon hosted by Chinese President Hu Jintao. When Nino Salukvadze of Georgia won the bronze medal in the 10 meter air pistol competition, she stood on the medal podium with Natalia Paderina, a Russian shooter who had won the silver. In what became a much-publicized event from the Beijing Games, Salukvadze and Paderina embraced on the podium after the ceremony had ended.
Terrorism has had an impact on the Olympic Games. In 1972, when the Summer Games were held in Munich, Germany, eleven members of the Israeli Olympic team were taken hostage by the terrorist group Black September in what is now known as the Munich massacre. The terrorists killed two of the athletes soon after they had taken them hostage and killed the other nine during a failed liberation attempt. A German police officer and 5 terrorists also perished. During the Summer Olympics in 1996 in Atlanta, United States, a bomb was detonated at the Centennial Olympic Park, which killed two and injured 111 others. The bomb was set by Eric Robert Rudolph, an American domestic terrorist, who is currently serving a life sentence for the bombing. Security at the Olympic Games has been an increasing concern and focus for Olympic planners since the terrorist attacks of 11 September 2001.
 IOC rules for citizenshipThe Olympic Charter requires that an athlete is a national of the country they compete for. Dual nationals may compete for either country, as long as three years have passed between when the competitor competed for his former country. However, if the NOCs and IF involved agree, the IOC Executive Board may reduce or cancel this period. This waiting period exists only for those who previously competed for one nation and want to compete for another. If an athlete gains a new or second nationality, they do not have to wait any designated amount of time before participating for the new or second nation. The IOC is only concerned with issues of citizenship and nationality after individual nations have granted citizenship to athletes.
 Reasons for changing citizenshipSometimes, athletes become citizens of new nations solely for the purpose of competing in the Olympics. This usually happens either because people are drawn to sponsorships and training facilities in places like the United States or because an athlete does not qualify in their original country. This is usually because there are many qualified athletes in an athlete’s home country and they want to be able to participate as well as help the team of their new country. Between 1992 and 2008, there were about fifty athletes that have immigrated to the United States to compete on the US Olympic team after having previously competed for another nation.
 Citizenship changes and disputesOne of the most famous cases of changing nationality for the Olympics was Zola Budd, a South African runner who immigrated to the United Kingdom because there was an apartheid-era ban on the Olympics in South Africa. Budd was eligible for British citizenship because her grandfather was born there, but British citizens accused the government of expediting the citizenship process for her.
Other notable examples include Kenyan runner Bernard Lagat who became a United States citizen in May 2004. The Kenyan constitution requires that one renounce their Kenyan citizenship when they become a citizen of another nation. Lagat competed for Kenya in the 2004 Athens Olympics even though he had already become a United States citizen. According to Kenya, he was no longer a Kenyan citizen, leaving his silver medal in jeopardy. Lagat said he started the citizenship process in late 2003 and did not expect to become an American citizen until after the Athens games. Basketball player Becky Hammon was not being considered for the United States Olympic team but wanted to play in an Olympic Games, so she immigrated to Russia where she already played in a domestic league during the WNBA offseason. Hammon received criticism from Americans, including the US national team coach, even being called unpatriotic.
 Champions and medalistsThe athletes or teams who place first, second, or third in each event receive medals. The winners receive gold medals, which were solid gold until 1912, then made of gilded silver and now gold-plated silver. Every gold medal however must contain at least six grams of pure gold. The runners-up receive silver medals and the third-place athletes are awarded bronze medals. In events contested by a single-elimination tournament (most notably boxing), third place might not be determined and both semifinal losers receive bronze medals. At the 1896 Olympics only the first two received a medal; silver for first and bronze for second. The current three-medal format was introduced at the 1904 Olympics. From 1948 onward athletes placing fourth, fifth, and sixth have received certificates, which became officially known as victory diplomas; in 1984 victory diplomas for seventh- and eighth-place finishers were added. At the 2004 Summer Olympics in Athens, the gold, silver, and bronze medal winners were also given olive wreaths. The IOC does not keep statistics of medals won, but National Olympic Committees and the media record medal statistics as a measure of success.
 Host nations and cities The process of selection is carried out in two phases that span a two-year period. The prospective host city applies to its country's National Olympic Committee; if more than one city from the same country submits a proposal to its NOC, the national committee typically holds an internal selection, since only one city per NOC can be presented to the International Olympic Committee for consideration. Once the deadline for submission of proposals by the NOCs is reached, the first phase (Application) begins with the applicant cities asked to complete a questionnaire regarding several key criteria related to the organization of the Olympic Games. In this form, the applicants must give assurances that they will comply with the Olympic Charter and with any other regulations established by the IOC Executive Committee. The evaluation of the filled questionnaires by a specialized group provides the IOC with an overview of each applicant's project and their potential to host the Games. On the basis of this technical evaluation, the IOC Executive Board selects the applicants that will proceed to the candidature stage.
Once the candidate cities are selected, they must submit to the IOC a bigger and more detailed presentation of their project as part of a candidature file. Each city is thoroughly analyzed by an evaluation commission. This commission will also visit the candidate cities, interviewing local officials and inspecting prospective venue sites, and submit a report on its findings one month prior to the IOC's final decision. During the interview process the candidate city must also guarantee that it will be able to fund the Games. After the work of the evaluation commission, a list of candidates is presented to the General Session of the IOC, which must assemble in a country that does not have a candidate city in the running. The IOC members gathered in the Session have the final vote on the host city. Once elected, the host city bid committee (together with the NOC of the respective country) signs a Host City Contract with the IOC, officially becoming an Olympic host nation and host city.
By 2016, the Olympic Games will have been hosted by 44 cities in 23 countries, but by cities outside Europe and North America on only eight occasions. Since the 1988 Summer Olympics in Seoul, South Korea, the Olympics have been held in Asia or Oceania four times, a sharp increase compared to the previous 92 years of modern Olympic history. The 2016 Games in Rio de Janeiro will be the first for a South American country. No bids from countries in Africa have succeeded.
The United States has hosted four Summer and four Winter Olympics, more than any other nation. Among Summer Olympics host nations, the United Kingdom has been the host of two Games, and will host its third Olympics in 2012 in London. Germany, Australia, France and Greece are the other nations to have hosted the Summer Olympics twice. Among host cities, only Los Angeles, Paris, Athens and London have played host to the Olympic Games more than once – each holding that honor twice. With the 2012 Games scheduled to take place in London, the British capital will hold the distinction of hosting the modern Games three times, more than any other city.
Concerning the Winter Olympics, France has hosted three Games, while Switzerland, Austria, Norway, Japan and Italy have hosted twice. The most recent Games were held in Vancouver, Canada's second Winter Olympics and third overall. The next Winter Games will be in Sochi, Russia in 2014, which will be the first time this nation has hosted.
- Originally awarded to Chicago, but moved to St. Louis to coincide with the World's Fair
- Not recognized by the IOC
- Equestrian events were held in Stockholm, Sweden. Stockholm had to bid for the equestrian competition separately; it received its own Olympic flame and had its own formal invitations and opening and closing ceremonies, as with all its previous Games.
- Equestrian events were held in China's Hong Kong. Although Hong Kong has an independent National Olympic Committee from China, the equestrian competition was an integral part of the Beijing Games; it was not conducted under a separate bid, flame, etc., as was the 1956 Stockholm equestrian competition. The IOC website lists only Beijing as the host city.
