Dragnet was an American radio series, enacting the cases of a dedicated Los Angeles police detective, Sergeant Joe Friday, and his partners. The show took its name from the police term "dragnet", meaning a system of coordinated measures for apprehending criminals or suspects.

Dragnet is perhaps the most famous and influential police procedural drama in media history. The series gave audience members a feel for the boredom and drudgery, as well as the danger and heroism, of police work. Dragnet earned praise for improving the public opinion of police officers.[1]Actor and producer Jack Webb's aims in Dragnet were for realism and unpretentious acting.

He achieved both goals, and Dragnet remains a key influence on subsequent police dramas in many media.
