Big Brother 16 is the sixteenth season of the American reality television series Big Brother. The new season premiered on June 25, 2014 on CBS. It is the first season of the series to be broadcast in high definition. The season premiere was a two-night event, with the premiere episode airing on June 25 and the next episode airing on June 26. On August 4, 2014, it was announced that the 90-minute season finale would take place on September 24, 2014, making the length of the season 97 days. On September 24, Derrick Levasseur won the game in a 7-2 vote against Cody Calafiore.
Big Brother 16 was officially announced on September 12, 2013, a week before the finale of Big Brother 15. In March 2014, casting began with applicants being able to apply online or attend open casting calls throughout the country.
In June 2014, it was revealed that Big Brother 16 would be the first season of the series to be broadcast in high definition. Plans to finally transition the show to HD were made as early as Big Brother 13, but were hampered by logistical challenges due to the nature of the program's format, such as the amount of video footage that would have to be stored and processed, and the need to install HD-compatible cameras, wiring and post-production equipment. The house was also remodeled to benefit from the transition. Big Brother was the last primetime program across the five major networks to still be broadcast in 4:3 standard definition. Producers also noted that the HD cameras would also give them a variety of new shots and angles to use in the production.
Press interviews were filmed on June 17, 2014, the cast was announced on June 19, 2014 and the HouseGuests moved into the Big Brother house on June 20, 2014. Big Brother 16 began with a two-night premiere on June 25–26, 2014. On June 25, 2014, five days after the HouseGuests moved into the Big Brother house, eight of the 16 HouseGuests—Amber, Cody, Devin, Donny, Frankie, Joey, Nicole and Paola—were introduced, shown entering the house and taking part in the first HoH competition of the season, while on June 26, the eight HouseGuests who were not introduced the night before—Brittany, Caleb, Christine, Derrick, Hayden, Jocasta, Victoria and Zach—were introduced, shown entering the house and taking part in the second HoH competition. It was on the June 26 episode that the Team America and Battle of the Block twists were revealed.
