But another factor is that- especially for older stuff- nobody included licensing agreements for anything except broadcast & syndication rights. They simply didn't think about it...sometimes because there was no such thing as home video of any kind when the shows were created.
It sounds like this might have been the case with WKRP. According to wikipedia (for whatever that's worth), WKRP was shot on video instead of film to reduce royalties and there was only a 10-year syndication agreement. If all that's true, I'm guessing somebody interested in re-releasing the show would have to go back to all the original rights holders and renegotiate new deals -- which is probably considered unprofitable for a show that nobody under 35 remembers.
That's too bad, because I think we genuinely do lose a piece of valuable culture as a result.
