The series ended after 72 days, in which HouseGuest Mike "Boogie" Malin was crowned the Winner, and Erika Landin the Runner-up.

In September 2003, following the ratings success of Big Brother 4, Entertainment Weekly confirmed that CBS had renewed the series leading up until 2006,[1] ensuring three more seasons to air during the Summer time period.

This season featured a slight change to the schedule that was used in the previous edition, with episodes airing on Tuesdays, Thursday, and Sunday each week.

[19] The Thursday episode, which aired at 8 pm Eastern Time, featured the live eviction and subsequent Head of Household competition taking place.

The Sunday episode, which aired at 8 pm Eastern Time, featured the food competition and nomination ceremony, as well as some highlights from the previous days.

The web series aired thirty-minute episodes on weeknights, and allowed fans to call in and express their opinions on the events of the game.

For a small fee, they would receive daily video and text alerts about events in the house as well as exclusive "Diary Room" interview footage not available anywhere else.

In a twist only featured during this season, the Head of Household room's decor changed depending on who held the title that week.

Each week, the HouseGuests take part in several compulsory challenges that determine who will win food, luxuries, and power in the House.

[29] The nominee with the greater number of votes will be evicted from the House on the live Thursday broadcast, exiting to an adjacent studio to be interviewed by Chen.

These "Jury Members" will be sequestered in a separate house and will not be allowed to watch the show except for competitions and ceremonies that include all of the remaining HouseGuests.

In its place, the contestants who lost the food competition would be required to eat Big Brother Slop for the week, which has an oatmeal like texture to it.

Additionally, the player selection for the Power of Veto competition changed from the Head of Household and the two nominees being able to choose anyone they wanted to compete to a random draw occurring to decide the other three competitors.

He therefore won the Coup d'État, giving him the ability to overturn the Head of Household's nominations and replace them with two HouseGuests of his choosing.

Janelle Pierzina and Mike "Boogie" Malin returned for season 14 as coaches guiding the new HouseGuests, later entering to play the game themselves.

[35] George Boswell, Jason "Jase" Wirey, and Janelle Pierzina returned in season 10 to host a food competition along with other Big Brother alumni.

George Boswell, Bill "Bunky" Miller, Danielle Reyes, Lisa Donahue, Erika Landin, Michael "Cowboy" Ellis, and Kaysar Ridha attended the premiere of season 20.

Janelle Pierzina and Will Kirby also appeared on a special edition of The Price Is Right, competing with other past Big Brother players.

Danielle Reyes competed on the first edition of Big Brother Reindeer Games, a competition themed holiday spin-off.

[47] This prevented the backdooring strategy that had been started by Nakomis in her initial season, as all HouseGuests were eligible to compete for the Power of Veto.

If a pair's ball made it to the top of the ramp, the team had won food for the house on that day, as well as a catered meal.

[66] Shortly before the Power of Veto ceremony, Jase found out he was a potential replacement nominee and began throwing things around the backyard and engaging in numerous verbal arguments.

[67] On Day 22, George chose to use the Power of Veto to remove himself from the block, with Jase being nominated as the replacement nominee.

[78] Following his win, Mike kicked a pair of glass goggles, believing them to be plastic, and cut his foot open; the wound required stitches, though did not impact the game in any form.

The winning team, which consisted of Diane, Janelle, Will, Mike, Danielle, and James were the winners, and won an advanced screening of the film Talladega Nights: The Ballad of Ricky Bobby.

[41] On Day 29, Mike chose to use the Power of Veto to remove himself from the block, with Diane being nominated as the replacement nominee.

[94][95] For this week's eviction, James chose to use the power he had earned during the Head of Household competition and nullified Janelle's vote.

[103] That night, HouseGuests competed in a new version of the competition, in which they answered using a movable block; Janelle became the new Head of Household for the third time this season.

The viewers also voted for the Prom King or Queen, with this winner getting an advantage in the competition; Janelle was selected, however, could not compete as outgoing Head of Household.

[158][159][160][161] Color key: Big Brother: All-Stars had an average of 7.56 million viewers, a slight increase from the previous edition.
