This season, several houseguests have returned from past seasons of Big Brother. Will viewers return to watch this summer? Will this staple of the CBS schedule be cancelled or renewed for a 19th season? Stay tuned.

Hosted by Julie Chen, Big Brother typically airs three nights a week — Wednesdays (veto), Thursdays (eviction), and Sundays. This time around, the new contestants are Paul Abrahamian, Victor Arroyo, Corey Brooks, Paulie Calafiore, Bronte D’Acquisto, Bridgette Dunning, Zakiyah Everette, Jozea Flores, Glenn Garcia, Michelle Meyer, Natalie Negrotti,  and Tiffany Rousso. Returning houseguests from past seasons are Da’Vonne Rogers, Frank Eudy, James Huling, and Nicole Franzel.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly the 18-49 demo), the better the chances for survival. This chart will be updated as new ratings data becomes available — typically around 11:30am EST/8:30am PST. Refresh to see the latest.

8/3 update: CBS has renewed Big Brother for two more seasons — season 19 for Fall 2016 on CBS All Access, season 20 for Summer 2017 on CBS. Details here.

For comparisons: The Sunday editions of the 17th season of Big Brother averaged a 1.95 rating in the 18-49 demographic with 6.10 million viewers.

Note: These are the final national numbers (unless noted with an “*”). These are different from the fast affiliate numbers which are just estimates of the actual ratings. The final nationals are typically released within 24 hours of the programming or, in the case of weekends and holidays, a couple days later.
