Anthony Zuiker: (On the possibility of a fourth CSI show) I think three's enough. We don't want to kill the golden goose, so to speak. I think we've pretty much run the gamut. 'CSI' Las Vegas, Miami and New York makes nice sense as a trilogy. I think another one wouldn't be the smartest thing to do."
Anthony Zuiker: (On CSI) We have stiff competition going up against "Law & Order". And there were a lot more science-oriented shows [when New York debuted]. When Miami first spun off, there was "CSI", "Crossing Jordan" and maybe "John Doe"--we still had sort of a monopoly on the [forensic science genre]. Now I think there's probably fifteen or twenty shows on the air so it's been difficult to establish a vision for the show, and its own identity.
