Adam-12

Adam-12 follows the career of Officer Pete Malloy, who had decided to leave the LAPD after his young partner was killed in the line of duty. He has one night to go and for that last ride, he is assigned a rookie, fresh out of the police academy, to take out on his first night on the street. After that night, Malloy decides that he must stay around a little longer if Officer Jim Reed is going to survive his 9 month probationary period.
Adam-12, which was another "true-story" based television series from Jack Webb in the same vein as Dragnet and Emergency, was the first TV series to more realistically portray the joys and frustrations of being a police officer in the late 1960s through middle 1970s. This "new" attention to detail made the show a catalyst for uncounted numbers of people to enter law enforcement agencies when they became adults, the same way COPS has done since 1989.
"1-Adam-12" was the radio call sign of the patrol unit that Malloy and Reed worked. In Los Angeles, the first digit (1), represented the division worked. "Adam" is the LAPD designation for a 2-person patrol unit; "12" was the beat area assigned. Although, Malloy & Reed could be seen patrolling the streets all over Los Angeles from downtown to the Valley, they retained the division number 1, no matter where they were. In reality, you work the same district each day and are assigned a zone in that district.
The police station used throughout the series for exteriors was the then recently built (1965) Rampart Station, which is in actuality, Los Angeles, Division 2. Jack Webb was such a stickler for authenticity, that he had the Rampart substation's insides exactly duplicated in the sound stage for interiors.
Adam-12 remained popular during it's entire run, though it began to slip some in it's sixth season. This prompted the producers to free Malloy and Reed up from their district and start patrolling all over the L.A. area. Their assignments would now take them to LAX, the Los Angeles Harbor, the Foothill District, the West Valley area, Venice, Van Nuys, Hollywood and North Hollywood. Also included would be a two part episode where Reed and Malloy go airborne with an ASD helicopter unit.
