Route 66 is an American adventure crime drama television series that premiered on CBS on October 7, 1960, and ran until March 20, 1964, for a total of 116 episodes. The series was created by Herbert B. Leonard and Stirling Silliphant, who were also responsible for the ABC drama Naked City, from which Route 66 was an indirect spin-off. Both series employed a format with elements of both traditional drama and anthology drama, but the difference was where the shows were set: Naked City was set in New York City, while Route 66 had its setting change from week to week, with each episode being shot on location.

Naked City is an American police procedural television series from Screen Gems that aired on ABC from 1958 to 1963. It was inspired by the 1948 motion picture The Naked City and mimics its dramatic "semi-documentary" format. As in the film, each episode concluded with a narrator intoning the iconic line: "There are eight million stories in the naked city. This has been one of them."
