The Big Brother house is going high tech.

For the 20th anniversary season, the new Big Brother cast will find themselves in a house with “creative interactive spaces”. One of these is in the Head of Household room. Not only can the HOH spy on the other players but now they will also be able to speak with them through a video intercom system.

There is also a new twist. The BB App Store twist will be unveiled on the Canada Day episode (8:00-9:00 PM, ET/PT). Viewers will be able to “get the houseguests trending” and that will lead to special powers or punishments later on. On premiere night there will be three challenges which will also lead to a special power and two punishments.

Big Brother 20 debuts with a three-hour, two-night premiere event Wednesday, June 27 (8:00-10:00 PM, ET/PT) and Thursday, June 28 (9:00-10:00 PM, ET/PT) on Global.

Following the two-night premiere, Big Brother 20 will air Sundays (8:00-9:00 PM, ET/PT), beginning July 1; Wednesdays (9:00-10:00 PM, ET/PT), beginning July 4; and Thursdays (9:00-10:00 PM, live ET/delayed PT), beginning July 5, featuring the live eviction show hosted by Julie Chen.
