Julie Chen, has been the host of the American version of Big Brother since its debut in 2000. During the first season, she was widely criticized in the media for her heavily scripted, wooden delivery in her interaction with the studio audience and in the interviews on the live programs. This has earned her the nickname the "Chenbot" among the fans, a title she has proudly come to embrace.
Two contestants were under the required age of 21 to be eligible to apply to be on Big Brother. This was because both were a part of the twist that season. Michelle was 19 in Big Brother 4 as one of the exes in the X Factor twist. Daniele was 20 in Big Brother 8 for the enemies twist with her estranged father.

Controversy occurred during a live HOH competition of the final four in season 9 where Julie stated 'There is another pre-existing relationship in the house, true or false.'

This controversial answer altered the outcome of the competition and ultimately the game.

A technical malfunction during a live HOH competition in season 7 had certain house guests lights and buzzers unable to work properly. Even with obvious errors, Erica was named HOH. Later that evening Julie Chen presented a new HOH competition over the intercom after producers explained that fairness needs to stay intact for all competitions and therefor the competition needed to be redone. Without lights and buzzers, the competition was presented the old fashioned way where Janelle ended up winning.
Season 7 introduced Big Brother slop as the food restriction that replaced peanut butter and jelly from seasons 2-6. All-Stars is also the only season where the HOH bedroom is specifically re-designed each week to match the HOH winner and their individual personality.
In season 1 Julie Chen announced the winner inside the house with the final 2 then making their way outside to a large crowd. Seasons 2-4 had the cast inside the house pulling their own keys while Julie remained in the studio and on the screen while the final 2 emerges to a small number of family and friends outside the house. Beginning with season 5 the cast joins Julie in the studio where she names the votes through the tv screen to the final 2 who are in the house and then emerge to a large crowd outside the house, which has stayed on every season since. In addition streamers fly when the winner walks out of the house starting with season 11.
