Big Brother 21 (American season)

Prior to the live finale, a public vote is held to determine who would win the title America's Favorite HouseGuest and a prize of $25,000.

Big Brother follows a group of contestants, known as HouseGuests, who live inside a custom-built house outfitted with cameras and microphones recording their every move 24 hours a day.

[12] Jeff Schroeder returned to host pre-season interviews with the cast after being replaced by Celebrity Big Brother alumnus Ross Mathews for the previous season.

Christie, Cliff and Kathryn, along with Sam, Jack and Nicole, participated, with Big Brother 20 winner Kaycee Clark returning to host.

The Head of Household, Jack, Kemi and Jessica, along with Isabella, Michie and Sam, participated, with Big Brother 20 runner-up Tyler Crispen returning to host.

The others, getting caught in the lie, started getting furious and made Isabella and Nick change their minds and completely gun after Nicole to get her out this week.

Nick and Isabella believe they secured the votes to evict Nicole while the Six Shooters progressively become more committed on the plan to blindside Cliff and send him home.

Now on the Nomination Block as the replacement for Michie, Isabella begins campaigning to stay in the House and makes compelling arguments.

Shown in a flashback, the full story of the chaotic, yet unsuccessful effort to flip the vote to evict Kathryn was explained.

The vote starts flipping to evict Analyse after Christie talks with Michie about targeting Nick for future weeks.

As a part of Prank Week, on Day 64, HouseGuests had to stay up during the night to listen to an exorbitant number of bird names and sounds as a joke to make the HouseGuests think that was for the Head of Household competition, but before the comp, they were informed about Prank Week and that the competition had nothing to do with bird sounds and names.

Cliff, Jessica, and Nicole receive their punishment: they must make pies and then smash them in the face of the person the announcer tells them to.

Later, Big Brother 20 alumns Bayleigh Dayton and Chris "Swaggy C" Williams, who are currently engaged, appeared as guests to host the Head of Household competition.

Cliff won and made his way back into the game, while David, Ovi, and Kemi were forced to immediately leave the house for good.

On the August 1, 2019 eviction episode, it was revealed that America would vote for three HouseGuests who would compete against one another, with the winner being given immunity for the week, the runner-up being given a punishment and the loser being a third nominee.

[116] The house also features two diary rooms where the HouseGuests can privately share thoughts or send requests to producers of the series.

[120] Meanwhile, a full house tour with Chen Moonves and other photos were released through Big Brother's and CBS' social media outlets including Instagram,[121][122] Twitter[123][124] and Facebook.

[127] The living room features a birch-wood coffee table and a large and a 23-foot triangular window illuminated by LED lights.

[129] In the kitchen, many of the appliances have been redone in an attempt to blend them in with the rest of the theme, with an electronic campfire added to the center of the formal dining table.

[135] As part of a promotion for new CBS series Love Island, Sam Smith won a trip to Fiji in a Power of Veto competition.

Despite the decrease in ratings, CBS announced on September 5, 2019 that Big Brother was renewed for its twenty-second season and will premiere in the summer of 2020.

When people are in a house like that 24 hours a day under those conditions, it's difficult to hide an inconvenient truth about American culture and society.

"[142] However, the way CBS handled the situations was somewhat praised by viewers as they dedicated a time during the live finale to address them and let the HouseGuests explain themselves.

[143][144] Justin Carriero of The Young Folks wrote, "These HouseGuests got away with a lot and they avoided the blowback by being in jury, so they had no idea what storm was heading their way.

[147] Michie chose David Alexander and Kemi Fakunle, the season's only two black HouseGuests, Jessica Milagros, a Latina plus-size model and Cliff Hogg, the oldest person in the house.

[150] Big Brother is a reality show about a group of people who live together at times, the Houseguests may reveal prejudices and other beliefs that CBS does not condone.

Once the Live Feeds began, Jack Matthews started making obscene and prejudiced remarks about fellow HouseGuests Kemi Fakunle, Ovi Kabir, and Jessica Milagros, behind their backs.

[156] During Week 3, an incident involving the dominant "Gr8ful" alliance, which was partially shown during episode 10, was sharply criticized by the viewing audience.

[165] In an open interview with CBS executives, Big Brother was accused of giving "contestants of color unfair cuts or early eliminations" as well as editing out comments by HouseGuests that have been interpreted as racist.

[166][167] CBS executives defended editors of the show stating that it's difficult to edit days worth of content into 40 minutes.
