'CSI: NY,' CBS (2004-present)
The show is a second spinoff from predecessor and still-successful CSI. It follows the same procedural format, with police and forensic scientists solving mysterious crimes.
Why it’s still on -- and how much time it has left: All three CSIs remain on the network -- until the end of the 2011-12 season, anyway., Both NY and Miami were on the chopping block heading into May. NY was granted another season; Miami was not.
