Looks like you don't have to go home, but you can't stay here as CBS is closing-up it's Zoo for good after three seasons. Produced by CBS Television Studios and based on the 2012 novel of the same name by James Patterson and Michael Ledwidge, Zoo was an expensive series that was able to survive for three seasons based on an agreement between CBS Television Studios and Netflix. The streaming service agreed to cover a percentage of the cost of the series; and in return, was able to stream the show after its seasons were completed.
But as The Hollywood Reporter first reported, even with a financial safety net the series couldn't escape the curse of steadily declining ratings: averaging 2.65 million viewers in its third season, which is down from season two's average of 4.45 million viewers. Looking at the key 18-49 demo, the most recent season finale drew a 0.5 rating: though steady with the season premiere, the rating is actually down from the season two finale rating of 0.7.
Premiering in Summer 2015, CBS described the series as:
ZOO, based on the #1 bestselling novel by James Patterson, is a global thriller about a wave of violent animal attacks against humans sweeping the planet. In season three, the year is 2027, and the world has reached a tipping point: as the human population continues to dwindle due to the sterility problem, an equally devastating threat rises in the form of "the hybrids," an army of unstoppable lab-made creatures, hell-bent on destroying mankind. Although the team has become estranged over the past decade, Jackson, Jamie, Abraham, Dariela and Logan are forced to overcome their differences and reunite when they learn that Mitch is alive. As the planet's future hangs in the balance, the team must race to stop the hybrids and their creator – a shadowy figure with a startling connection to the team's past.
Starring James Wolk, Kristen Connolly, Nonso Anozie, Nora Arnezeder and Billy Burke, Zoo was produced by Jeff Pinkner (Fringe), Josh Appelbaum (Life on Mars), Andre Nemec (Star-Crossed) and Scott Rosenberg (Life on Mars). All four also served as executive producers on the series, along with James Mangold (Walk the Line), Cathy Konrad (Girl, Interrupted), Bill Robinson, Leopoldo Gout, Steve Bowen and Patterson.
