Big Brother (Finnish TV series) season 3

Big Brother 2007 was the third season of the Finnish reality television season Big Brother. It aired on SubTV in Finland, from 28 August 2007 to 2 December 2007, and lasted 97 days.

A number of contestants (known as "housemates") lived in a purpose-built house in Espoo, and were isolated from the rest of the world. Each week, each housemate nominated two of their peers for eviction, and the housemates who received the most nominations would face a public vote. Of these, one would eventually leave, having been "evicted" from the House. However, there sometimes were exceptions to this process as dictated by Big Brother, known as "twists".

Vappu Pimiä was the host of Big Brother Talk Show for the first time in this season; Janne Kataja hosted Big Brother Extra since Pimiä left Extra to host the Talk Show.

Housemates
There were a total of twenty housemates in this season of Big Brother. Twelve entered at the Launch, including Piia, who was the winner of a vote on an internet video site, and won a place in the house. Heli entered after Tiina M left the house after she found out she was pregnant. Four new housemates - Farbod, Niko, Suvi and Tiina H entered shortly after Henri's eviction. Aki was ejected for not disclosing important issues about himself during the casting process and was replaced by Jussi. Martina entered the house after Maxine's eviction, and left when she learnt of her grandfather's death, and was replaced by Riita, who was the final housemate to enter the house in this season.

Voting format
Any viewer may cast as many evict or save votes as they choose. Prior to eviction each housemates' evict votes were merged with their save votes; the housemate with the lowest number of save votes remaining after the merge is evicted.
