Cops (stylized as COPS) is an Americandocumentary/reality legal series that follows police officers, constables, sheriff's deputies, federal agents and state troopers during patrols and other police activities including vice and narcotics stings. It is one of the longest-running television programs in the United States and in May 2011 became the longest-running show on Fox with the announcement that America's Most Wanted was being canceled after 23 years. It follows the activities of police officers by assigning television camera crews to accompany them as they perform their duties. The show's formula follows the cinéma vérité convention, with no narration or scripted dialog, depending entirely on the commentary of the officers and on the actions of the people with whom they come into contact.
