Seasons and episodes
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 more infrequently on ABC beginning in 1989. The last film was broadcast in 2003. See List of Columbo episodes for more details.

DVD
As January 10 2012, Universal Studios Home Entertainment had released all episodes of Columbo on DVD. The episodes are released in the same chronological order as they were originally broadcast.

Because the Columbo episodes from 1989 to 2003 were aired very infrequently, different DVD sets have been released around the world. In the UK (Region 2), all episodes have now been released as ten seasons, with the tenth season covering the last 14 shows from "Columbo Goes to College" (1990) to the most recent "Columbo Likes the Nightlife" (2003). However in France, and The Netherlands (also Region 2) the DVDs were grouped differently and released as twelve seasons.

In Region 1, all episodes from seasons 8 are grouped differently; all the episodes that are originally aired on ABC were released on COLUMBO: The Mystery Movie Collection DVDs Many other sites such as IMDb, had even grouped the Columbo episodes into 13 seasons. Therefore, all episodes here will be arranged as it is in the UK release and only episode number will be called in this article.

Blu Ray release
To commemorate the death of Peter Falk, a complete series was released on Blu-ray in Japan, taken from new HD masters and original aspect ratio. The series includes 35 discs and is presented in a wooden box case.
