There's some blurring between the 70's and 80's here.

For example:

"Barney Miller is a comedy television series set in a New York City police station in Greenwich Village that ran from January 23, 1975 to May 20, 1982 on ABC."

Focusing on the 80's:

"St. Elsewhere is a U.S. drama television series that originally ran on NBC from October 26, 1982 to May 25, 1988. The series is set at St. Eligius, a decaying urban teaching hospital in Boston's South End neighborhood."

and

"Hill Street Blues is a serial police drama that was first aired on NBC in 1981 and ran for 146 episodes on primetime into 1987."
