Hill Street Blues is an American serial police procedural television series that aired on NBC in prime-time from January 15, 1981, to May 12, 1987, for 146 episodes. The show chronicles the lives of the Metropolitan Police Department staff of a single police station located on Hill Street in an unnamed large city, although the opening credits show scenes from the city of Chicago, contrasted with New York City inferences, including: a discussion, at the start of the eighth episode, of the police department running a summer camp for juvenile delinquents in New York's Allegany State Park; a stolen police vehicle being found in the East River in the 11th episode; and a mention, in the 13th episode, that Detective LaRue lives on the Lower East Side. The "blues" are the police officers in their blue uniforms.
