Big Brother Brasil 9

Big Brother Brasil 9 was the ninth season of Big Brother Brasil which premiered January 13, 2009 with the season finale airing April 7, 2009 on the Rede Globo television network.

The show is produced by Endemol Globo and presented by Pedro Bial. That season was officially confirmed since 2008 as part of a millionaire contract between international Endemol and Rede Globo.

The grand prize was R$1 million with tax allowances, with a R$100,000 prize offered to the runner up and a R$50,000 prize offered to the 3rd place.

At the end, Maximiliano Porto from Maricá, RJ, won the competition over journalist Priscila Pires with 34.85% of the final vote (0.24% lead), in the closest vote in the history of the Big Brother series.

General
There were twenty housemates (the largest number of contestants to date) competing for the grand prize, an increase over the previous season. The season lasted 85 days (one of the longest seasons of the show, tied with the fourth and seventh seasons), an increase of one week over the previous season.

The season introduced the notion of "The Battle," in which the house is separated into a luxurious half (A) and a poor half (B), with two teams of housemates constantly fighting for time in the luxurious half. The wall that divided the house was effective only in the first week. For the first time since the sixth season, the Finale Night featured a Final Three rather than a Final Two.

During the Show
At the launch night, there were eighteen housemates, but only fourteen entered the house. The remaining four contestants were locked for a week in a glass room located at a shopping mall in Rio de Janeiro.

At the end of the first week, viewers could vote one (later two) of the glass house housemates to enter the house. Emanuel (41% to save) and Josiane (37% to save) were chosen. Both entered in the house on day 9 (January 21, 2009).

On day 31 (February 12, 2009), two new housemates (Maíra Cardi and André) entered the house. They lived in a glass house (this time, located at the garden) for 4 days. Viewers could vote "yes" or "no" for both stay in the house. They chose "yes" with 59%.

This is the second time Big Brother Brasil has allowed a contestant of another Big Brother to stay in the house (He was Ricardo "Ricco" Venancio, the winner of Big Brother Africa 3). Ricco entered on day 47 (February 28, 2009) and stayed in the house for 4 days. He left the house on day 50 (March 3, 2009).

Ana Carolina Madeira (one of the most popular contestant of the season) was the housemate with the most number of nominations for eviction in Big Brother Brasil history, being seven times on the chopping block.

White Room Controversy
The "White Room" was the subject of controversy in the media, viewed as a cruel tactic of psychological torture. This kind of sensory deprivation is also used in CIA interrogations, which only increased the criticism of the block.

Voting History
The voting table below records whom each housemate voted to nominate on the diary room during his or her time in the House. The Head of Household vote (cast in front of the other housemates) automatically nominate one housemate from eviction. Then, the other housemates voting and if the vote is tied, the HOH breaks the tie (all this types of vote count for the total number of nominations received).
