COPS follows police officers, constables, and sheriff's deputies during patrols and various police activities by embedding camera crews with their units. The show's formula adheres to a classic cinéma vérité ethos. With no narration or scripted dialog, it depends entirely on the commentary of the officers and on the actions of the people with whom they come into contact.

Eighteen to twenty castaways will compete against each other on Survivor. All castaways will compete to outwit, outplay, outlast and ultimately be crowned Sole Survivor.
