Fortunately, when TV Land (or maybe it was Nick) did run Dennis The Menace a number of years ago, I was able to get a few episodes on VHS. Wish I had a lot more of that, as well as "Car 54" and others. Also when I had my C band dish up, I was able to get shows like "Please Don't Eat The Daisies" on WOR.
Surely we old farts over 50 have enough buying power to support advertising for ONE classic TV channel catering to our tastes! It's a funny thing TV Land, Sci-Fi and others use these older shows to build up an audience, then we're dumped! Even the Game Show Network got started by running B/W episodes of "Password", "To Tell The Truth", "The Price is Right" and other game show classics.
