Pinoy Big Brother: 737

Pinoy Big Brother: 737 is a series of editions held under one season, 737. This is the second special and the twelfth overall season of the franchise, based on the Dutch reality show Big Brother. The show started on June 20, 2015. This season coincides with the tenth year of Big Brother in the Philippines. It was hosted by Toni Gonzaga, Bianca Gonzales, Robi Domingo and Enchong Dee. Mariel Rodriguez, who served as the last celebrity houseguest, returned to the show after five years to host the Big Night. It began airing on June 20, 2015 on ABS-CBN and ended on November 8, 2015, lasting 142 days, only falling 13 days short of Unlimited. The show airs 10:00pm (PST) every Mondays to Sundays.

The season started with the entrance of the first batch of housemates: the teen housemates. They will stay inside the House for seven weeks, until August 8, 2015. The next batch of housemates—the regular housemates—entered on Day 50. The four finalists of the teen batch returned to the House on Day 99. After the final eviction on Day 133, the public determines the winner of each batch. On the two-part finale, the third and fourth placers of each batch were announced. The votes went back to zero and the lines re-opened for the remaining housemates of each batch to determine the winners.

In the launch night, the first 7 revealed that the teen housemates will be staying in the house for seven weeks.3 means that three celebrity houseguests, Mariel, Enchong and Karla, will be staying in the House. On August 21, 2015, during the tenth anniversary celebration, the second 7 was revealed to mean that the regular housemates and the winners of previous seasons will join to raise P3,000,000 in seven weeks, to build a community of 20 houses for 20 families.

On November 8, 2015, Miho Nishida & Jimboy Martin were declared winners of this season.

Less than a month after the conclusion of Pinoy Big Brother: All In, the Pinoy Big Brother production team announced that work was underway for developing the sixth regular season. On January 28, 2015, ABS-CBN released a teaser with highlights of the past seasons and editions, including the big winners.
