Premiere Ratings Surge
CBS’s “Big Brother” returned on Thursday, July 9, 2026, with a 90-minute Season 28 premiere that attracted 3.88 million live + same-day viewers according to Nielsen Big Data + Panel. Variety reported an average of 3.9 million viewers, marking the series’ largest opening audience since Season 23’s July 2021 debut (4.3 million). The episode also set a six-year record for the most-watched Thursday-night “Big Brother” premiere, the previous high occurring in August 2020.
Recent Ratings Trajectory
Season 27’s premiere drew just under 3.2 million viewers, and the Thursday-night average for that season settled at 3.2 million. Compared with those figures, Season 28’s debut reflects a 22 % increase over the prior year’s premiere and a 21 % rise over Season 27’s Thursday average. The boost follows a period of declining viewership that began after the 2021 peak.

Network Response
CBS cited the Nielsen and Social Content Ratings data in a statement emphasizing the “strong start” and “robust fan engagement” for the season. Executive producers Allison Grodner and Rich Meehan, along with creator John de Mol, highlighted the new “Time Trip” twist—introducing reality veterans Angela Murray (Season 26), Rick Devens (Survivor Seasons 38 & 50), and Rachel Reilly (Seasons 12, 13, 27)—as a driver of renewed interest. The network also noted that Season 28 will become the first primetime series to reach 1,000 original episodes later this summer, underscoring its historic longevity.
