Big Brother 4 (Courtesy Wikipedia, the free encyclopedia)

In the fourth season of Big Brother, the American reality TV show, aired thirty-three episodes during the summer of 2003 from July 8 to September 24.

Rule Changes

X-Factor

The big twist for the year was The X-Factor. Eight HouseGuests were introduced, only to have five HouseGuests' exes compete against them in the game. This quickly became messy, as Scott, a HouseGuest who had his ex-girlfriend move into the house, had a violent outburst, and subsequently told the house that he had a sexually transmitted disease. He was disqualified and evicted from the game.

Golden Power of Veto

Another twist, introduced in the last veto contest of Big Brother 3, was the Golden Power of Veto, in that if a nominated person won such a veto, they would be allowed to take themselves off consideration for voting, which was not allowed when the veto was introduced originally the year before.

Event ordering

Yet another twist in the game occurred when Jun won HoH in Week 8 of the competition. The Veto competition would be held before Jun would make her nominations. The reason being was that Jun, as HoH, won a special trip outside of the Big Brother house to attend the 20th Annual MTV Video Music Awards. Her disappearance (as she entered the Diary Room and never returned) played a part in the Veto Competition, as the houseguests had to guess where Jun was. Jun returned, and nominated Jee, her ex-boyfriend, and Alison. However, Alison won the Veto, and used it on herself, forcing Jun to put Robert in her place. Despite Robert being a replacement for Alison, Jee was unanimously evicted 2-0.

Jury

One last twist to the format included a jury of seven who would decide the outcome of the game. When the game got down to nine players, the evictees formed the jury. The jury format eliminated America's need to break a tie if necessary, as done before in Season 3 (though Lisa won 9-1). The sequestered jury was introduced after many outcry among fans when Danielle lost season 3 arguably due to evicted houseguests seeing her diary room sessions. From season 4 on, the sequestered jury saw only competitions and evictions.

Final outcome

The final veto competition occurred at the final four, not at the final five like the previous year. The Diamond Veto was of the utmost importance to the game. At the competition, Alison emerged victorious, winning the power to remove herself from the nomination block and casting the sole eviction vote. Despite having promised both Jun and Erika to take them to final two, Alison tearfully chose to evict Erika.

The final Head of Household competition was in three parts. Alison beat Robert in the first part (the endurance portion) after having promised to take him to the final two. In the second part, Jun easily beat Robert by completing a mental challenge based on events that had taken place in the house. Therefore, Jun and Alison faced each other in part three of the competition, with both having pledged to take the other to final two. After eight questions based on their ex-boyfriends Jee and Justin, the women were tied on four correct answers apiece. The tiebreaker question was "How many days did you date your ex for?", to which Alison answered zero days and Jun answered one million. Therefore, Alison emerged as the final Head of Household for the season and chose to evict Robert from the house.

The jurors stated their disgust and disappointment with the conduct and gameplay of both Alison and Jun. Despite Alison's prowess in competitions, the jury in the end voted Jun as the winner of Big Brother 4 in a 6-1 vote. Jun received votes to win from Dana, Justin, Jack, Jee, Erika, and Robert, while Alison only received a winning vote from Nathan.

Memorable Events

• This season featured the first act of sex between houseguests on the show when contestants Amanda and David had sex under the covers in the Head of Household room. The DVD that was released featured uncensored moments from the season that weren't allowed for broadcast, including this encounter.

• For the second time in four seasons, a Big Brother houseguest was removed from the show when Scott was evicted for an angry rampage which included throwing furniture and which frightened some of the houseguests.

• Contestant Michelle, at age 19, was and remains (as of Season 8), the youngest houseguest in the show's history.

Voting history

A record of the votes cast, stored in a voting-table, shows how each HouseGuest voted to evict throughout his or her time in the house. The Head of Household and the nominees are not allowed to vote, but in the event of a tie, the Head of Household will break it. Twists to the normal nominations process are noted, such as immunity from nomination and eviction (referred to as "exempt") and double evictions. The last seven evictiees of the season are part of the Jury of Big Brother 4. The seven Jury Members vote for the winner during the Finale.
