For clarification purposes, for me to define a show as rare or obscure, it has to meet the following criteria:
Short-run (2 seasons or fewer)
No airings of the full series anywhere, post-1980
No film copies in circulation among collectors
When Ted Turner bought MGM, he ran almost every series they owned on TNT. Some he ran the whole series of (Hondo, National Velvet, Travels of Jamie McPheeters, etc.). Others he ran a majority of the episodes but not all of them (Mr. Novak, Jericho, Man Called Shenendoah, etc.). Then there were some shows that ran a couple or a very few episodes, like Cain's Hundred, The Thin Man and The Lieutenant. The only shows in that library that he didn't run at all were Asphalt Jungle, Sam Benedict, Many Happy Returns, Adam's Rib, The Eleventh Hour, Harry's Girls, The Islanders and maybe a couple of others. The good news is that he reportedly transferred the entire catalogue to tape so that when Warner goes ahead with their Burn on Demand plans and does TV, we won't get issues with the elements like we would with the other companies which haven't done anything with their lesser seen shows. That doesn't mean that the shows that are Warner shows were transferred also, just all of the former Turner shows at least.
