To watch Big Brother live in 2025, the best option is to stream it on Paramount Plus with Showtime, which offers live streaming of every episode as well as Big Brother live feeds. The show airs on CBS at 8pm ET/PT on Wednesdays, Thursdays, and Sundays. For those without cable, CBS can be streamed via services like Fubo, and free live feeds are also available on CBS's streaming service Pluto TV starting from July 13, 2025. Subscribing to Paramount Plus Premium allows live episode streaming and access to live feeds. Additionally, viewers in Canada can watch on Global TV, and a VPN can be used to watch from outside the US. The live feeds can be found on the Paramount Plus platform under the Big Brother show's live feed section. A cable login might be necessary for live feed access on Paramount Plus.
