Pinoy Big Brother

Pinoy Big Brother, more popularly known by its abbreviated title PBB, is the Philippine version of Big Brother. The word Pinoy in the title is a colloquial term used to describe the Filipino people. The show first aired on August 21, 2005 on ABS-CBN, Studio 23, and its international channel, TFC in various countries worldwide. The uncut 24/7 version of the series can also be seen on the internet through paid-online streaming video subscription via TFCNow, and through cable network SkyCable. The show is currently hosted by Toni Gonzaga, Mariel Rodriguez, Bianca Gonzalez, and Robi Domingo.

Other essential elements of the Big Brother franchise are present, such as weekly and daily challenges, the confession room, and the voice known only as "Big Brother," sometimes referred to as "Kuya" (Tagalog for an elder male sibling). Pinoy Big Brother uses their tagline "Teleserye ng Totoong Buhay" or the "Real Life Soap Opera".

It follows the same premise as its many foreign counterparts around the world where in a number of Filipinos volunteered to live inside a house for a certain number of days.

The elimination process in the show is the reverse of the original Dutch format. At the start of the elimination process, the "housemates" (as the contestants are referred to) vote for which two (sometimes more if there are ties or if Big Brother hands out an automatic nomination) fellow housemates they should eliminate. Once these nominations are chosen, the viewer votes come into play. For a week viewers are asked to vote, via SMS or voice messaging through PLDT's hotline (later abolished in favor of vote cards), for whoever they wanted to stay longer in the house. The housemate with the least viewer votes is eliminated. In the final week, the one with the most viewer votes will win the grand prize package, usually includes house and lot, a car, a business franchise, home appliances, and a holiday, and is given the title the Big Winner.
