'Big Brother' will return with its new season this June following a controversial break. The fate of the show seemed uncertain at the end of season 20 last summer, after Les Moonves, CEO of CBS, stepped down from his position following numerous accusations of sexual assault.

But it is back and running as Moonves wife, Julie Chen Moonves, resumes her iconic role as the host of 'Big Brother' for the 19th year.  Here is everything we know about Big Brother Season 21:

Release date

'Big Brother' season 21 will premiere on June 25, but it will be a two-night event, with the show carrying over to June 26, at its usual airtime of 8 pm ET


The series follows a group of contestants, known as the HouseGuests, who live together in a custom-built home under constant surveillance. The HouseGuests are completely cut off from the outside world and can have no communication. The HouseGuests are evicted from the house on a weekly basis and the winner takes home a $500,000 grand prize.


The cast is unknown as of yet but CBS has the pressure to pick socially well-behaved individuals especially after a number of guests in the past were accused of being racist and sexist. This article will be updated when the casts are announced.

The US 'Big Brother' was based on an originally Dutch TV series of the same name created by producer John de Mol in 1997. The Dutch media tycoon is one of the men behind production companies Endemol and Talpa and is worth about US$ 1.5 billion. Besides 'Big Brother,' de Mol also produced 'The Voice', 'Fear Factor', 'Love Letters' and 'Deal or No Deal'.


Julie Chen Moonves, the longstanding host of 'Big Brother', will officially return for season 21. Her speculated return to the show comes after allegations involving her husband, Les Moonves. Chen made a statement in support of her husband, but quit her role as a co-host of 'The Talk'. Her husband stepped down from his position as the Chairman and CEO of CBS Corporation in September 2018, after numerous allegations of sexual harassment and abuse. 


CBS dropped their first promo teaser for 'Big Brother' without giving the slightest hint of when it's premiering and who all are the HouseGuests. The teaser just had the voiceover hyping fans to get ready for a house full of total strangers.  But the second teaser, which dropped on May 21 has a little more information on the premiere date and offers glimpses of the HouseGuests.


Where to watch

The summer reality series will return with hourlong episodes on June 25 and 26 at 8 pm on CBS. Following the two-night premiere, 'Big Brother' will air on Sunday, June 30 at 8 pm with its regular three-weekly-episode format.
