During the Final Five eviction episode of Big Brother 22 (US), an advertisement for casting new players for the next season was aired, leading many to assume Big Brother was getting a 23rd season. Although the CBS casting page immediately stated that it was accepting applications for season 23[1], an official renewal announcement from CBS wasn't made until October 28, 2020, the day of season 22's finale, confirming that season 23 was due to air in the summer of 2021[2].
Development
Casting
Following in the footsteps of Big Brother Canada 9, CBS announced a new diversity pledge on November 9, 2020, which would require that Big Brother and the rest of their reality programming to have at least 50% of its cast be black, indigenous or people of color, starting with Big Brother 23.[3]
