Law and Order is an American police procedural and lawful dramatization TV arrangement, made by Dick Wolf and some portion of the Law and Order establishment. It initially circulated on NBC and, in syndication, on different link systems. Law and Order debuted on September 13, 1990, and finished its twentieth and last season on May 24, 2010. At the season of its cancelation, Law and Order was the longest-running wrongdoing dramatization on American primetime TV. After The Simpsons, both Law and Order and Gunsmoke tied for the second longest-running scripted American primetime arrangement with progressing characters.
