Both "Big Brother" and "Zoo" have been renewed for new seasons at CBS, network president Glenn Geller announced on Wednesday at the Television Critics Association summer press tour.
"Big Brother," one of the top-rated summer series on the air today, got renewed for two seasons, meaning the show will air through at least 2018.
Since it premiered on CBS in the summer of 2000, the show has consistently finished among the summer's top-rated series in young demographics. So far this summer, all three weekly broadcasts of "Big Brother" rank among the top 10 programs in adults 18-49.
In addition, since its premiere, the current season of "Big Brother" is the most social series on TV, according to Nielsen Social, and total streams across digital platforms are up 33 percent over last year.
It is produced by Emmy Award-winning producer Allison Grodner and Rich Meehan for Fly on the Wall Entertainment, in association with Endemol Shine North America.
"Zoo," based on the No. 1 bestseller by James Patterson, is a global thriller about a wave of violent animal attacks against humans across the planet. It is produced by CBS Television Studios. Jeff Pinkner, Josh Appelbaum, Andre Nemec, Scott Rosenberg, Michael Katleman, James Mangold, Cathy Konrad, James Patterson, Bill Robinson, Leopoldo Gout and Steve Bowen are executive producers.
