CBS’s summer 2025 primetime lineup will be Big Brother heavy, with the network expanding coverage of the long-running reality competition series with the most televised hours since its debut. CBS will air 90-minute season 27 episodes on Wednesdays and added Big Brother: Unlocked, a new behind-the-scenes look at BB, on Friday nights.
Big Brother: Unlocked is hosted by three All-Stars and will feature special guests, never-before-seen footage, and exclusive interviews. Unlocked will air on Fridays at 8pm ET/PT beginning July 25, 2025.
“Big Brother follows a group of people living together in a house outfitted with 94 HD cameras and 113 microphones, recording their every move 24 hours a day,” reads CBS’s synopsis. “Each week, someone will be voted out of the house, with the last remaining Houseguest receiving the grand prize of $750,000.” Recent winners include Kaycee Clark (season 20), Jackson Michie (season 21), Cody Calafiore (season 22), Xavier Prather (season 23), Taylor Hale (season 24), Jag Bains (season 25), and Chelsie Baham (season 26).
Julie Chen Moonves will return as host.
