Big Brother Brasil 20
Big Brother Brasil 20 was the twentieth season of the reality show Big Brother Brasil, shown by Rede Globo from January 21, 2020 to April 27. The show is produced by Endemol Shine and presented by Tiago Leifert.
The grand prize is R$1.5 million with tax allowances, plus a R$150.000 prize offered to the runner-up and a R$50.000 prize offered to the housemate in third place.
The season originally featured 18 housemates divided into two groups of 9: "Celebrities", composed of actors, singers, professional athletes and social media personalities, and "Civilians", composed of everyday Brazilians. On week 2, 4 new potential housemates entered the game as part of a [|twist], with 2 of them actually moving into the house, bringing the number of housemates up to 20.
On March 12, 2020, Rede Globo suspended all live audiences for their shows due to the coronavirus pandemic in Brazil. On March 16, or Day 56 inside the house, all of the current housemates were notified of the current events outside of the house, including the pandemic. Globo also moved the show's broadcast timeslot from 10:30 p.m. to 10:45 p.m. due to the extent of news coverage on their primetime national newscast. Sunday's live nominations shows were moved from 11:30 p.m. to 11:00 p.m. due the network cutting their main entertainment programms of that day.
As of March 31, 2020, the season broke three worldwide voting records. Guilherme's eviction against Gizelly and Pyong on week 6 reached the mark of 416 million votes, surpassing the old mark of 202 million votes casted on the previous season. Pyong's eviction against Babu and Rafa on week 8, broke the record of simultaneous voting with 1.4 million votes casted per minute, with 385 million votes counted. Then, on week 10, a new record-breaking number of 1.5 billion votes resulted in Felipe's eviction against Manu and Mari, and entered the Guinness World Record for "Most public votes received by a television programme".
In order to celebrate the show's 20th season anniversary, competitions and twists from previous seasons were revived and scattered again throughout this season. The season was originally planned to last 94 days, the longest of the series, ending on April 23, 2020. On April 13, 2020, Rede Globo announced that the season was extended in 4 days, with the live finale moved to April 27, 2020, for a total of 98 days.
On April 27, 2020, anesthesiologist Thelma Assis won the competition with 44.10% of the public vote over digital influencer Rafa Kalimann and actress & singer Manu Gavassi.
