Besides weird TV channels like MeTV (?), the Hallmark Movies & Mysteries channel seems to show episodes of “Columbo”. Check your local listings for details.
Although it seems like full episode clips are taken down for copyright issues, there are plenty of classic “Columbo” clips on Youtube! Just search for “columbo” to watch!
“Columbo” is only available through Netflix on DVD so by the time you’re reading this it’s probably too late to get it for Columbo Day. Maybe you live close to a Netflix distribution center and can drive over there?
Don’t you sort of wish Blockbuster was still around? Would’ve been nice to be able to drive over to your local store and rent a few seasons :(
