Big Brother 2021 start time, channel

The first episode of Big Brother 2021 will broadcast at 8 p.m. ET today (Wednesday, July 7). It's on CBS and will be available live and on-demand on Paramount Plus.

Place your bets! It's finally time to watch Big Brother 2021 online. Season 23 of the CBS reality series is kicking off tonight with a cast of 16 houseguests, all strangers, who are moving into the BB Beach Club in the premiere episode today! And the stakes are higher than ever. 

This year's contestants include a flight attendant, make-up artist, start-up founder, farmer, kindergarten teacher, forensic scientist and an attorney, among others. They'll live together through a summer filled with big risks and big rewards, where one wrong gamble could cost them eviction. And by the end of episode 1, the houseguests will face a brand-new twist when they're given a double-or-nothing offer that may be too good to turn down.

Host Julie Chen returns to oversee the proceedings, which will move to three episodes a week starting July 11. Plus, CBS is partnering with Clubhouse to present events throughout the summer. Fans will have the chance to join conversations with Big Brother alums, insiders and experts. More details to follow. 

The cast is entirely stocked with complete strangers for the first time in several seasons. They range in age from their 20s to 40s. One houseguest, Christie Valdiserri, had to leave the show before move-in due to a positive COVID test. She will be replaced by Claire Rehfuss.

The 16 houseguests will be living in the BB Beach Club, which executive producer Allison Grodner has described as a "house-meets-boutique hotel on the ocean, with some really fun elements that play into the theme." And this year will play heavily into the theme of gambling. 

Here's everything you need to know about how to watch Big Brother 2021 online.

How to watch Big Brother 2021 with a VPN

Big Brother fans, if for some reason you've had to leave your own "bubble" — or you can't get CBS where you are for some strange reason — and you can't watch the Big Brother 2021 premiere, you're not out of luck. With a virtual private network, or VPN, you can appear to be surfing the web from your home town (or somewhere that blackouts won't hit), and access the same streaming services you already paid for. 

Not sure which VPN is right for you? We've tested many different services and our pick for the best VPN overall is ExpressVPN. ExpressVPN offers superb speeds and excellent customer service, and IPVanish's low pricing is shocking.


We think speed, security and simplicity make ExpressVPN second to none. During our tests, we saw fast connection times, and we're impressed by the service's ability to access more than 3,000 services spread out across 160 locations in 94 countries.
