About the show
Zoo is a new dramatic thriller series that stars the incredibly handsome James Wolk (Mad Men) as Jackson Oz, a zoologist who notices strange animal behavior that ultimately leads to an onslaught of attacks on humans around the world. Based on the eponymous bestselling novel by James Patterson and Michael Ledwidge, season 1 of the show premiered on June 30, 2015 on CBS.
Jackson Oz (Wolk) is a renegade American zoologist who spends most of his time navigating safaris in the African wildness. His adventures eventually lead him to witness strange patterns of animal behavior that include ferocious, cunning, and sometimes downright coordinated assaults on humans. Through a series of events he is thrust into a race to solve the mystery of the pandemic before humans literally run out of places to hide.
Current season, solid ratings and renewal potential
Wildly popular with viewers, Zoo season one premiered to solid ratings but stumbled against a bit of controversy when animal rights advocacy group PETA protested the show’s use of real animals during filming. Overall, the series debuted with 8.18 million viewers, but declined slightly to an average of about 6.4 million throughout its 13 episode run. That didn’t seem to bother CBS much though, and the network announced that it would renew Zoo for season 2, which premiered on CBS on June 28, 2016 with a two-hour special. The danger level escalates in the current season, as the vicious mutation moves to its next stage, and the infected animals begin attacking infrastructure and pushing the environment towards becoming completely uninhabitable. How will the team lead by Jackson Oz manage to survive and save the human race? The second season premiere drew 5.14 million viewers, and scored a share of 3 and a 0.8 demo rating. The subsequent episodes` viewership went down by over 10%, but did not give way in either the share or the demo rating. Whether or not the series will be renewed depends largely on the viewership during the remainder of this season, so please stay tuned for relevant news.
