Big Brother Season 27 to Premiere with 90-Minute Episode
CBS announced today that Big Brother Season 27 will air the most original hours of programming in 25 years since the show’s debut. The programming will include extended 90-minute Wednesday episodes and Big Brother: Unlocked on Friday nights throughout the season.
Big Brother Season 27 kicks off with a 90-minute premiere on Thursday, July 10 (8:00-9:30 p.m. ET/PT), followed by a 90-minute Sunday episode on Sunday, July 13 (8:00-9:30 p.m. ET/PT).

Julie Chen Moonves returns as host. Paramount+ subscribers and Pluto TV viewers can continue to catch all the action on the Big Brother live feeds.
In the 90-minute premiere of its 27th season, Big Brother welcomes an all-new group of Houseguests into the Big Brother House. Expect the unexpected with more hours than ever this summer and a season full of twists and turns.

After its premiere, the series will air on Wednesdays (8:00-9:30 p.m. ET/delayed PT), expanded from its regular 60-minute episodes, followed by hour-long shows on Thursdays – featuring live evictions – and Sundays (8:00-9:00 p.m. ET/delayed PT).
Then get ready for Big Brother: Unlocked as three BB All-Stars offer never-before-seen broadcast footage from the house, exclusive interviews, surprise guest appearances, and unprecedented behind-the-scenes access.

Former Houseguests share firsthand insight and expertise as they analyze gameplay, assess the competition, and give their insider’s perspective every other Friday starting on Friday, July 25 (8:00-9:00 p.m. ET/PT).
Paramount+ with SHOWTIME subscribers will have access to stream live via the live feed of their local CBS affiliate on the service, as well as on-demand.
