The following is an episode list for the crime fiction television series Columbo. After two pilot episodes, 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 part of The ABC Mystery Movie from 1989 to 1990 and less frequently starting in late 1990. The last installment was broadcast in 2003.
Because the Columbo episodes from late 1990 to 2003 aired infrequently, different DVD sets have been released around the world. In Region 2 and 4, all episodes have now been released as 10 seasons. Seasons 8-9 reflect the two seasons aired as part of The ABC Mystery Movie, and the 10th season covers the last 14 episodes from "Columbo Goes to College" (1990) to the series finale, "Columbo Likes the Nightlife" (2003).[1] In France and the Netherlands (also Region 2), however, the DVDs were released as 12 seasons.[2] In Region 1, all episodes from season 8 are grouped differently; all the episodes that were originally aired on ABC were released in four volumes under the banner COLUMBO: The Mystery Movie Collection.[3] For the sake of clarity, all episodes in this article are arranged as they appear in the UK release.
