In years to come the crime drama will be divided into pre and post-technology eras. We watched the first Prime Suspect last night. Early on somebody sings "Happy Birthday" into a radio phone but there's no appearance from a mobile at any point. We're supposed to be impressed by the fact that the star has a bleeper. There is one computer in the office but it's used to store about five word processing documents. Police are dazzled by the prospect of being on television. And somebody mentions having got some money out of "one of those cash machines".
It was made in 1991.
