美国早期电视：侦案剧

　　This episode deal with police and crime show on early American television. Dragnet started on radio and it seemed a natural to take to TV. Producer and star Jack Webb demanded a flat, emotionless delivery of all dialogue that became the show's trademark. The Untouchables was a huge success but was among the first shows to raise public concern about violence on the small screen. Mannix featured a caring private eye while Mission: Impossible had intricate plots. I Spy was the first show to have an African-American in a leading role. Hawaii Five-O also featured a largely ethnic cast, another first. Women were well represented in the genre with the The Girl from U.N.C.L.E., Honey West and Police Woman all featuring female protagonists. Columbo and the The Rockford Files had their own take on crime and were hugely successful.
