Law & Order is an American police procedural and legal drama television series, created by Dick Wolf and part of the Law & Order franchise. It originally aired on NBC and, in syndication, on various cable networks. Law & Order premiered on September 13, 1990, and completed its 20th and final season on May 24, 2010. At the time of its cancellation, Law & Order was the longest-running crime drama on American primetime television. Its record of 20 seasons is a tie with Gunsmoke (1955–1975) for the longest-running live-action scripted American prime-time series with ongoing characters. Although it has fewer episodes than Gunsmoke, Law & Order ranks as the longest-running hour-long primetime TV series. Gunsmoke, for its first six seasons, was originally a half-hour program.

Set and filmed in New York City, the series follows a two-part approach: the first half-hour is the investigation of a crime (usually murder) and apprehension of a suspect by New York City Police Department detectives; the second half is the prosecution of the defendant by the Manhattan District Attorney's Office. Plots are often based on real cases that recently made headlines, although the motivation for the crime and the perpetrator may be different.

The show has been noted for its revolving cast over the years. Among the longest-running main cast members were Steven Hill as District Attorney Adam Schiff (seasons 1–10), Jerry Orbach as Detective Lennie Briscoe (seasons 3–14), S. Epatha Merkerson as Lieutenant Anita Van Buren (seasons 4–20), Sam Waterston as Executive Assistant District Attorney Jack McCoy (seasons 5–20; later District Attorney) and Jesse L. Martin as Detective Ed Green (seasons 10–18).
