Why Was It Cancelled? This show’s ratings were down notably in its third season and it seemed certainly to be headed to cancellation which CBS confirmed with an October cancellation announcement. However, that network’s other Summer series Salvation, which had approximately the same ratings average, received a renewal nod. Both shows have streaming deals (Netflix for Zoo and Amazon for Salvation) that make them profitable for CBS on the front end, so it seems like both should have received renewals. Zoo is more expensive to produce, though, so perhaps that factored into the decision. But I expect that the show’s fans will be lobbying streaming partner Netflix to give it at least a fourth season if not more.
