Julie Chen Moonves Brings Big Brother Season 28 Premiere to July 9
big brother season 28 premiere is set for Thursday, July 9, at 8 p.m. ET on CBS, and the launch runs 90 minutes. Julie Chen Moonves returns as host, giving the franchise a familiar on-air anchor as it enters a season built around a longer opening hour and a bigger schedule commitment.
Julie Chen Moonves Returns
Chen Moonves is back for the new season, and that continuity matters because Big Brother is still one of CBS’s most schedule-dependent reality franchises. The premiere arrives as the show prepares to become the first series to reach 1,000 original episodes in primetime, a milestone that puts the longevity of the format front and center rather than treating the launch as just another summer return.
The season will not move in a straight weekly pattern after the opener. Following the premiere, Big Brother will air on Wednesdays from 8 p.m. to 9:30 p.m. ET, with hour-long Thursday shows built around live evictions and Sundays at 8 p.m. ET. For viewers, that means the new season opens with a wider window before settling into a split schedule that keeps the live-game mechanics on a tighter Thursday clock.
July 10 Expands The House
Big Brother: Unlocked returns on Friday, July 10 at 8 p.m. ET, extending the franchise’s reach beyond the main episodes. The companion series will include exclusive footage from inside the house, extended interviews, surprise guest appearances, and behind-the-scenes access, while also adding a live studio audience for the first time ever. That makes the summer rollout more than a simple premiere week; it is a two-show push designed to keep the conversation moving between the main episodes.
Paramount+ with Showtime subscribers will be able to stream live through the live feed of their local CBS affiliate on the service and also watch on demand. Paramount+ Essential subscribers will not get live streaming, but they will have on-demand access the day after the episode airs, which creates a clear split in how quickly different subscribers can follow the season. The practical effect is simple: the live game remains available for some subscribers in real time, while others will be one day behind the broadcast cycle.
1,000 Episodes In Primetime
Season 28 is the one that pushes Big Brother to 1,000 original episodes in primetime, and that number gives the July 9 premiere more weight than a routine summer launch. A franchise does not last that long by accident; it lasts because the network keeps a slot open for it, and because the format still pulls enough value from live evictions, weekly scheduling, and companion programming to justify the space.
For viewers, the takeaway is straightforward: the premiere is not just earlier on the calendar than the rest of the season’s rhythm. It is the start of a 90-minute opening, a second 90-minute episode on July 12, and a summer schedule built to keep the house visible across multiple days each week. If you follow the show through broadcast or streaming, the next few days set the pace for how the season will be delivered.
