Big Brother 1

Big Brother 1 was the inaugural season of the show, Big Brother. It premiered with 10 strangers living in a house for three months. It concluded when Elisabeth Cash was crowned the winner with votes from America.

Season 1 of Big Brother is radically different from following American seasons of the series. Every week, Housemates would nominate two fellow housemates and the two or more housemates with the most nominations were eligible for banishment. American viewers could then call a 1-900 number and cast a vote to evict a HouseGuest. There was no Head of Household, Power of Veto, or Food Competitions, but rather the HouseGuests would have to complete Weekly Tasks (also called Week Long Challenges) to win rewards for the house.

There were 6 episodes every week: a one-hour live eviction show, and five 30-minute daily recaps.

Development
Romer stated "The show is all about human interactions. It's people who are, loving each other, hating each other. They fight, they cry, they laugh -- all emotions, we'll see in the house." In a later interview, Romer added "The first thing people think of when they hear the Big Brother idea are adult, trashy things in the house. The major activity in the house [...] That's not what the show is about." The series was one of the first reality shows to air in the US, and required a crew of over 150 people.

Hosts
The host of the show is the same host as Sims: Survivor and Sims: The Amazing Race; Seryza.

Casting
Houseguests Ben and Natalie appeared on America's Got Talent. Marissa appeared on Hell's Kitchen. Trevor and Ethan had worked in modeling. Jeff made an appearance on a radio talk show. Ryan appeared on WWE. Elisabeth originally applied for Sims: Survivor, but was recruited for Big Brother. Helen was a motivation speaker for troubled teens and young adults. Stacy worked as a news reporter.

Airing & Schedule
The series initially aired five nights per week, though a sixth episode was later added into the schedule. The addition of a sixth episode per week caused the live banishment episode to move to Wednesday instead of Thursday. Four of these episodes were half-hour daily recap episodes, while one episode was an hourly-long weekly recap; the sixth episode was the live banishment.

Theme Song
The theme song for the series, known as "Live", was performed by Jonathan Clarke. It was played during the closing credits of each episode, and segments of the theme were played throughout the show.

Live Feeds
Viewers of the series could also watch the live feeds in the house, which were available for free on the official website. The feed was edited for music copyrights and to protect the privacy of some contestants. The feeds also featured a disclaimer for users under the age of 21, due to unedited aspect to the feeds.

The House
The house used for the first season was a one story house with two bedrooms, a kitchen and dining room, and one bathroom. The house was an estimated 1,800 square feet.

Throughout the house, there are a total of 28 cameras making all areas of the house visible to the cameras, and 60 microphones.During their stay in the house, the HouseGuests were required to wear microphones at all times, ensuring everything they said in the house was heard. Throughout the house the walls are lined with two way mirrors, with a production team filming behind them. The bedrooms featured infrared imaging cameras, allowing the cameras to continue filming while the rooms were dark.

The design of the house included bad feng shui, clashing colors and positioning. The house featured bright colors as part of its theme, with the kitchen being a bright blue and the living room yellow. The two bedrooms in the house were identical, with both featuring a bunk bed and three single beds. The bathroom featured one toilet, one shower, a washboard and a washtub. The Red Room was where HouseGuests were required to share their thoughts on the events in the house, and were often given tasks. The backyard of the house featured a patio area where the HouseGuests could sit outside. The backyard also featured a chicken coop, and the HouseGuests were able to use the eggs from the chickens as food.
