Speaking for myself, I've been noticing the same thing for 1980's era shows in genres I'm interested in. I'm around a decade younger, where I was a kid of the late-1970's and 1980's. I was mainly into cheesy action type tv shows, with lots of gunfire, explosions, destruction, car chases, etc ... and other forms of physical violence. (Shows like The A-Team, Knight Rider, Airwolf, Miami Vice, Dukes of Hazzard, MacGyver, etc ...). In the 1980's cheesy action tv show genre, at this point it appears to be mostly slim pickings left. Most of the major action shows and some of the lesser known ones, have already been released on dvd. I've been reading through wikipedia and other websites, searching for other 80's action shows I forgot about or missed completely. So far I haven't found many which greatly interest me. I've also been looking into action and cop type tv shows from the 1950's, 1960's, 1970's and 1990's. With the exception of shows I watched in reruns, for some reason very few of these non-80's action/cop type shows have struck an "emotional resonance" for me. (I've been "blind buying" the dvds of some of these non-80's shows, such as: Baretta, Renegade, The Commish, early seasons of Hawaii Five-O, Dragnet, etc ... ). As far as I'm concerned, to me these shows are not much different than watching episodes of modern shows like CSI, Law & Order, etc ... At this point, I don't have much hope in seeing many further dvd releases of yet-to-be-released cheesy action type tv shows, which could interest me. B&W tv shows aren't the only niche, where this is happening.
