Premiered: September 13, 1990, on NBC
Rating: TV-14
Premise: Durable cops-and-lawyers procedural with gripping headline-inspired storylines and two distinct halves: the investigation of the crime, followed by the prosecution of the case in court. Superbly acted by an ensemble cast and filmed in New York, the series debuted in 1990 and is chasing the 'Gunsmoke' record---20 years---as TV's longest-running prime-time series. 'L&O' has flourished despite many cast changes over the years, and has spawned three spin-offs, the latest being 'Trial by Jury.'
