Bahrain, Fiji, Ivory Coast, Jordan, Kosovo, Puerto Rico, Singapore, Tajikistan, and Vietnam all won their first gold medals, as did the group of Independent Olympic Athletes (from Kuwait).

It is not just about getting ads out there but it is about a targeted and very carefully planned campaign.The final voting was held in Copenhagen on 2 October 2009, with Madrid and Rio de Janeiro considered favorites to secure the Games.

On 26 June 2011, it was reported on Around The Rings that Roderlei Generali, the COO of the Rio de Janeiro Organizing Committee for the Olympic Games, resigned just one year after taking the job at ROOC.

Rio's historical downtown underwent an urban waterfront revitalization project known as Porto Maravilha, covering 5 km2 (1.9 sq mi) in area.

The project aimed to redevelop the port area, increase the city center's attractiveness, and enhance Rio's competitive position in the global economy.

The second warehouse of 90,000 square meters in Duque de Caxias, near the roads that provide access to the venues, contained all the equipment needed for the sporting events.

The clothing worn by the volunteers included yellow polo shirts and jackets, beige trousers, white socks, and green trainers, which they collected from the Uniform Distribution and Accreditation Centre.

Volunteers also wore photo accreditation badges which were allocated to officials, athletes, family members, and media, allowing them to gain access to specific venues and buildings around the site.

[32] As legacy projects, organizers intended to introduce a wider array of public transport options, upgrade the infrastructure of the favelas to provide improved transport and access to utilities, upgrade Rio's sewer system to remediate the level of pollution in the Guanabara Bay,[32][33] and plant 24 million seedlings to offset the expected carbon emissions of the Games.

To reduce emissions, the Olympic cauldron was designed to be smaller than previous iterations, using a kinetic sculpture to enhance its appearance in place of a larger body of flames.

[24][36] The Future Arena, the venue for the handball competitions, was designed as a temporary modular structure whose components could be reconstructed after the Games to build schools.

[40] The ceremony highlighted aspects of Brazilian history and culture, and featured a segment narrated by Fernanda Montenegro and Judi Dench with an appeal to environmental conservation and the prevention of global warming.

[5] The ceremony included the inaugural presentation of the Olympic Laurel, an honor bestowed by the IOC on those that have made "significant achievements in education, culture, development and peace through sport"; the trophy was awarded to Kenyan athlete Kipchoge Keino.

[41][45][46] Following the opening ceremony, a public cauldron was lit in front of the Candelária Church by Jorge Gomes, a 14-year-old Brazilian athlete who had escaped from poverty to train as a runner.

A number of events, most notably in aquatics, beach volleyball and track and field, were scheduled with sessions and matches occurring as late as 10:00 p.m. to midnight BRT.

This practice was also beneficial to Globo; a Brazilian critic noted that the network very rarely preempts its primetime telenovelas, as they are among the highest-rated programs in the country.

In another segment, introducing the athletes, singer Roberta Sá channeled Carmen Miranda, the fruit-headdress-wearing, mid-century Hollywood diva who endures as a beloved camp figure.

[86] In the United States, NBC offered 4K content downconverted from the 8K footage and with HDR and Dolby Atmos support, to participating television providers.

IOC board member Richard Carrión described the agreement as "unprecedented", touting that "by working with Brazil's leading media organizations, we are confident that this represents a great deal for Olympic fans in the region.

The Best Olympic Sports Production was awarded to Beach Volleyball, produced by Geoff Johnson and directed by Greg Breakell and Gary Milkis.

Gelli defended the allegations, stating that the concept of figures linked in embrace was not inherently original, as it was "an ancient reference" and "in the collective unconscious".

In 2014, Operation Car Wash, an investigation by the Federal Police of Brazil, uncovered unprecedented money laundering and corruption at the state-controlled oil company Petrobras.

In early 2015, a series of protests against alleged corruption by the government of President Dilma Rousseff began in Brazil, triggered by revelations that numerous politicians were involved in the Petrobras affair.

To prevent puddles of stagnant water that allow mosquitoes to breed, organizers announced plans to perform daily inspections of Olympic venues.

The WHO dismissed the request, stating that "cancelling or changing the location of the 2016 Olympics [would] not significantly alter the international spread of Zika virus", and that there was "no public health justification" for postponing them.

[126] The governor of Rio de Janeiro also highlighted the fact that London faced security problems, with a terrorist attack occurring just a day after it was awarded the 2012 Summer Olympics.

[127] On 21 July 2016, two weeks before the scheduled start of the Games, the Brazilian Federal Police broke up an Islamic jihadist terrorist cell named Ansar al-Khilafah Brazil by arresting 12 people.

In June 2016, they reported they were unable to fully carry out their work, and noted intimidation by armed Federal Security Service (FSB) agents.

[129] After a Russian former lab director made allegations about the 2014 Winter Olympics in Sochi, WADA commissioned an independent investigation led by Richard McLaren, which found corroborating evidence, concluding in a report published in July 2016 that the Ministry of Sport and the FSB had operated a "state-directed failsafe system" using a "disappearing positive [test] methodology" (DPM) from "at least late 2011 to August 2015".

[130] In response to these findings, WADA announced that RUSADA should be regarded as non-compliant with respect to the World Anti-Doping Code, and recommended that Russia be banned from competing in the 2016 Summer Olympics.
