Which CSI spin-off was set in New York City?

The CSI spin-off set in New York City was CSI: NY. It premiered on CBS in 2004 as the third series in the CSI television franchise, following CSI: Crime Scene Investigation and CSI: Miami.

The series centered on the New York City Police Department's forensic team, led initially by Detective Mac Taylor, played by Gary Sinise. Its cases used familiar CSI techniques such as DNA analysis, fingerprints, ballistics, and digital evidence, but placed them against a distinctly New York backdrop.

CSI: NY is easy to confuse with the other franchise titles because each show uses the same basic procedural format. CSI: Miami was set in Miami and led by Horatio Caine, while CSI: Cyber focused on FBI cybercrime investigations. CSI: Vegas, by contrast, returned to the franchise's original Las Vegas setting.

The New York series ran for nine seasons and ended in 2013. Its setting was not merely part of the title: locations and landmarks across the city were regularly used to shape the team's investigations and the show's visual identity.
