What I think is interesting about it is how totally random the reruns appear to be. They show them in no particular order, and there often times isn’t a true rotation with the other mystery movie series. The reruns of 1975-76 are maybe the oddest. No episode of “Columbo” (new or rerun) aired at all after November 2 or before February 1. But there were three “Columbo” telecasts in a row on May 2 (new episode), May 9 (rerun) and May 16 (rerun). There was a rerun on June 20 and then no other “Columbo” telecasts at all until September 5 and 12, two weeks in a row at the very end of the summer. Was this a network strategy or just totally random? “McCloud” and “McMillan & Wife” have some bizarre patterns at times, too.
