The house

The Big Brother House was built next to the buildings of broadcaster VTM at Medialaan 3 in Vilvoorde. It was built in less than 4 months, with a one-month construction vacation. Because the housemates would live in the house, there had to be a lot of administration done and there wasn't enough time. It is said the mayor of Vilvoorde, Jean-Luc Dehaene made it possible the administration was completed in time. The same building plans of the Dutch Big Brother house were used. The house was 212 m² and the garden was 240 m². Central in the house were two hidden walkways which formed across where the crew could film the housemates everywhere. There were 26 cameras and 60 microphones everywhere even in the toilet. Although the camera in the toilet was discussed a lot in media, it was never used in the show.^[1]

For the second season, a net covered the garden to obstruct messages from the outside thrown into the garden. An isolation room was added to the house. It was 4m² and had a chemical toilet. In the third season, the garden was completely covered with a glass ceiling.^[2][3] It was demolished in 2005.^[4]

The second house was built for the fifth season at the same location as the first one, in less than six months. The house was created as one open space surrounded by walkways for the crew and cameras. There were 60 microphones and 34 cameras. In the open space, everything was made out of glass – even the wall and the three showers. The glasshouse meant no privacy for the housemates. There was also a loft which had more luxury. The housemates had no space in the open air but a covered courtyard.^[5] The house was built so it could be easily reshaped as a television studio. This happened in July 2007 when Big Brother was scrapped and broadcaster JIMtv moved in.^[6]

For the 2021 season, for the first time, the cooperation for Big Brother between Flanders and the Netherlands, a new house was built in Amsterdam, next to the Johan Cruyff Arena at a parking lot of Endemol Shine in only a few months. The house was 300 m². There were 125 cameras, 100 indoor cameras and 25 outdoor cameras, and 39 speakers.^[7]

Changes of the concept

Since the start of its first season in September 2000, Big Brother Belgium went through numerous changes in its concept. Here are some significant examples of the progress of modifying the rules of the original game:

• "Only the housemates have to decide which of them gets nominated.": changed in season 3 were halfway to the season the viewers nominated and the housemates vote to evict and in season 4 were the viewers voted for their favorite housemates (unknown to the housemates) and the housemates vote to evict one of those housemates (to a secret location).
• "None of the housemates know each other before entering the house.": changed in season 5 with a couple in a romantic relationship entering the house and in season 6 there was a couple of friends, two sisters, a team of exes, two nieces, a romantic couple, a father and adoptive son who entered as pairs.
• "The prize money is a certainty": changed in season 6 where the prize money was reduced for every lie that was told (and detected by the lie detector).
• "The complete household lives together in one group": changed in season 4 with the most popular housemates at a secret location and the remaining housemates at the Big Brother house. In season 5 the season started with some housemates living in the secret loft.
• "Only the winner receives prize money": changed in season 3 where every housemate had his own budget. When the housemate evicted they received the remaining budget.
• "The housemates get no information from outside": changed in season 2 where the housemates were informed about the 911 terrorist attack.
• "The housemates live isolated in a house": changed in season 3 when housemates received tasks to do outside the house.

The beginning

On 3 June 2000, A special show Big Brother – De Start (Big Brother - the Start) was launched after a match with the Red Devils.^[10][11] The special was 30 minutes and had professors like philosopher Etienne Vermeersch and scientists like astronaut Dirk Frimout discussing social isolation. There were also testimonials of top athletes and ex-prisoners. The special was a call for participants. In two days there were 7500 letters from people who wanted to participate.^[12]

Participants were screened thoroughly. They had long questionnaires, conversations with the producers, psychological tests and conversations with a psychologist. Editor-in-chief Bart Verbeelen later stated that even some participants were followed by a private detective. Since the show already made some controversy before it was even aired, the producers wanted to make sure the housemates would be mentally healthy.^{[13] [14]}

On 3 September 2000, the kick-off of the first season aired and it was very successful.^[15] The daily episodes had more than 800,000 viewers on average. Every live show reached more than 1 million viewers. Big Brother was in the top 10 ratings weekly. After a call from housemate Steven Spillebeen for wax, more than 140 wax pots were thrown in the garden. Since the concept of this reality show was new, there was a lot of attention for Betty Owczarek who was often shown naked and for Bart Van Opstal & Katrijn Verlinden who were the first couple to have sex on Flanders television. Housemate Jeroen Denaeghel and other housemates experienced Stockholm syndrome where they developed sympathy for Big Brother and its house and were scared to leave the house. Housemates were instant celebrities.^{[16] [17]} It was the most visited website in Belgium in 2000.^[18] More than 5000 people were in the audience when Steven Spillebeen was declared the winner of the first season.^[19] The highlight of the finale reached 1,895,000 viewers. Because of the success of the program, Spillebeen had to stay the first 2 weeks undercover.^[20] Big Brother was very successful for the first season in Belgium.^[21] Not only the program had high ratings but also the official website was visited a lot. Because of the high demand for the 12 free cameras for live streaming, the site crashed a few times. In total, the camera's were more than 9 million times used for free viewing. 70.000 people visited the website daily and 4.2 million people weekly. The website had 75 million hits during the whole season.^[22] It was the most visited website in Belgium in 2000.^[23]

Continuation

The first season was the launch of huge success for the Big Brother franchise in Flanders. But every season had less impact. Producers stated that only the first season was real reality television. It was completely new for the makers of the program, the audience and the housemates. Housemates in later seasons knew what to expect and often hoped for an entertainment career rather than having a good or interesting time in the house. Editor-in-chief Bart Verbeelen also believed the producers started to experiment too quickly from the original concept and focusing more on conflicts.

Beforehand the second season were two spin-offs. The reality documentary Het leven na Big Brother (Life after Big Brother) documented the celebrity life of the housemates of the first season and a celebrity version Big Brother VIPs 1. Although Big Brother was broadcast at Kanaal 2, both spin-offs were broadcast at the bigger channel VTM. Both spin-offs were in the top 20 ratings of 2001, Big Brother VIPs 1 ranking at 9th place and with 1,161,300 viewers and Het leven na Big Brother ranking at 16th place.^[24]

13,000 people wanted to be a housemate for Big Brother 2. The second season was launched in September 2001. It started with a twist, 11 male housemates and only 1 female housemate entered the house on the opening night.^[25] In every province of Flanders, there was a Big Brother pub. And viewers could watch the housemates all the time on a pay-TV channel. The second season was still successful in the ratings, especially the live shows. The show got more criticisms. Following a party where housemates lost control after drinking alcohol, many viewers complained about the images of the kissing and suggested sex between 3 couples. The producers also censored the view of naked housemate Detlev and fellow housemate Irena who got in a large water tank.^[26] Commentators believed that night determined the whole season. It's the one thing viewers remember about the second season and the one housemate who acted properly was voted the winner at the end of the series.^[27] The finale was the 8th highest-rated show in 2001. The live shows of the second season still had more than 1 million viewers. Pay television CanalDigitaal which offered a 24/24 live stream had 20% more subscribers during the season.^[28]

Following the criticism of season 2, the producers changed a lot for the third season in 2002 and even added new twists, like a mole. Housemates were selected out of 4,500 candidates. Although the producers called the season its best season to date because of its colorful housemates, the audience thought it was the most boring season.^[29] The ratings started to slip.

In 2003, Big Brother All Stars launched beforehand the fourth season. The fourth season was built around a huge twist. The original plan was the housemates were "evicted" to a secret place by housemates and the most unpopular housemates would be mass evicted halfway the season. But because without being evicted and unfriendly housemates, the Big Brother house became a hostile place. Five housemates left the house voluntarily after many conflicts and bullying. The twist had no effection because there was eventually only one unpopular housemate left. There was also criticism about animal abuse when housemates Kristof, Mathousca and John had to kill a chicken. The producers apologized and made some tasks about charity and animal welfare by the end of this season. The season was the least popular and the rating continued to drop. Daily episodes got 300,000 viewers. Caused by ongoing criticism and a change of program directors at VTM, Big Brother was axed for an undetermined time in 2004. The house was demolished.^[30]

First revival

Big Brother returned with the fifth season in 2006. A new house was built and the concept was rethought.^[31] The season was well received.^[32][33] A Big Brother VIPs 2 followed. In the sixth season "Zero privacy" in 2007, the show was introduced a lie detector. During the kick-off show, housemates entered the house in pairs. Viewers complained about the boring housemates. Producers tried to spark interest by changing half of the housemates into new ones and adding two actors in the house. Ratings dropped very fast. The broadcast schedule of the live shows was also changed to reach more viewers. At the final on 4 June 2007, there was no call for future housemates. A few weeks later, the producers stated that Big Brother wouldn't be coming back for an indefinite time.^[34]

Second revival

In July 2020, it was revealed by RTL 5 and VIER that a new season in cooperation by the Netherlands and Flanders-Belgium would air in 2021.^[35] Three seasons followed in the following years.
