Columbo

Columbo is an American crime drama television series starring Peter Falk as Lieutenant Columbo, a homicide detective with the Los Angeles Police Department. After two pilot episodes in 1968 and 1971, the show originally aired on NBC from 1971 to 1978 as one of the rotating programs of The NBC Mystery Movie. Columbo then aired on ABC as a rotating program on The ABC Mystery Movie from 1989 to 1990, and on a less frequent basis from 1990 to 2003.

Columbo is a shrewd and exceptionally observant homicide detective whose trademarks include his rumpled beige raincoat, unassuming demeanor, cigar, old Peugeot 403 car, love of chili, and unseen wife (whom he mentions frequently). He often leaves a room only to return with the catchphrase "Just one more thing" to ask a critical question.

The character and show, created by Richard Levinson and William Link, popularized the inverted detective story format (sometimes referred to as a "howcatchem"). This genre begins by showing the commission of the crime and its perpetrator; the plot therefore usually has no "whodunit" element of determining which of several suspects committed the crime. It instead revolves around how a perpetrator known to the audience will finally be caught and exposed. The clues Columbo finds to help him solve the case are sometimes revealed to the audience beforehand, but often not until the episode's end.

The series' homicide suspects are often affluent members of high society; it has led some critics to see class conflict as an element of each story. Suspects carefully cover their tracks and are initially dismissive of Columbo's circumstantial speech and apparent ineptitude. They become increasingly unsettled as his superficially pestering behavior teases out incriminating evidence. His relentless approach often leads to self-incrimination or outright confession.

Episodes of Columbo are between 70 and 98 minutes long, and they have been broadcast in 44 countries. The show has been described by the BBC as "timeless" and remains popular today.
