Firstly, to people who were in the first wave of collectors, for lack of a better term, classic would consist of everything prior to the VHS/Beta era. That started in the late 70s but not too many people were consistently recording TV shows at that point. I would say that by the mid-80s, many were. So shows like The Wonder Years for instance, I know 3 people just among my friends who recorded the whole series off ABC. The same would hold true for just about any show from the last 25 years. So "classic" would be, prior to the era when home recording became common. Regarding companies, we have CBS/Paramount, Timeless, MPI, Virgil Films (or whatever they are calling themselves this month), Infinity and Shout Factory as the most active. Image is working on Thriller but I don't think I've bought anything from them since Naked City and that was at least 5 years ago. Smore is pretty much dormant. VCI puts out nice stuff but their release schedule is on a snails pace. The other "majors" Warner, Fox, Sony and MGM are all out of the business of releasing pre-1980s shows. At least Fox (and MGM, whom they control) are willing to license stuff out. Warner won't even do that. I think our only hope is if this burn on demand thing someday takes off but that could be years from now.
